Dovetail Games (DTG), a trading name of RailSimulator.com Ltd (RSC), is a British simulation video game developer and publisher established in 2008 by former Electronic Arts executive Paul Jackson, Fund4Games backers Tim Gatland and Charlie McMicking, and a development team from Kuju Entertainment.

Key Information

Originally focused on developing new content for Kuju Entertainment's Rail Simulator, they would go on to produce successors RailWorks/Train Simulator and Train Sim World, as well as fishing and flight simulation games.

In April 2023, Dovetail Games announced its acquisition by Focus Entertainment.[1]

History

[edit]

RailWorks' predecessor, Rail Simulator, was developed by Kuju Entertainment, the same company that developed Microsoft Train Simulator with Microsoft. With the release of Rail Simulator in October 2007, Kuju Entertainment finished development and disbanded the development team, turning its attention to the next project.

Knowing the potential of their proprietary game engine, and with backing from Fund4Games (Tim Gatland and Charlie McMicking), and support from the South East England Development Agency (SEEDA), a new company was set up called Rail Simulator Developments Ltd (RSDL) from some of the core members of the initial development team with the specific aim of fulfilling continued development of the brand and supporting users and third-party developers with add-on projects. RSDL produced two patches to the core simulator, developed and released add-ons, helped the release of third-party products, and visited exhibitions to promote the simulation and provide support for users via several community websites.

In April 2009, the formation of a new company was announced.[2] Jackson, Gatland and McMicking went on to set up RailSimulator.com Ltd (RSC), employing many of the original creative team, along with Steve Bainbridge (previously of Electronic Arts and GAME stores) and Duncan Best (previously British Academy Video Games Awards, ELSPA and Director of the London Games Festival).[3]

Development switched to a new version of the software called RailWorks, which would be released on Steam. This change heralded a break from Electronic Arts being the publisher in Europe and rights over the source code for Rail Simulator being transferred to single ownership by RailSimulator.com Ltd.[4] After improving the software, they launched RailWorks in June 2009. The company has released yearly updates since then, with the latest version, Train Simulator Classic, released in April 2022.

On 9 December 2013, it was announced that RailSimulator.com has changed its name to Dovetail Games.[5] The company said that it was in the early stages of developing a range of completely new simulation products to sit alongside Train Simulator, and this broader perspective required a new company name.[5]

Dovetail Games announced on 1 July 2014 its first new simulation product; a fishing simulation game titled Euro Fishing (initially Dovetail Games Fishing), utilising Epic Games' Unreal Engine 4 architecture and released for PC on 4 November 2014, with more formats to follow. The company also announced that it is laying the foundation to using Unreal Engine 4 in future versions of Train Simulator.[6]

On 9 July 2014, Dovetail Games announced that it has signed a licensing agreement with Microsoft to release Microsoft Flight Simulator X: Gold Edition on Steam in late 2014, titled Microsoft Flight Simulator X: Steam Edition. It includes content that was provided with the original FSX: Gold Edition which includes FSX: Deluxe Edition, the Acceleration expansion pack and both official Service Packs and repackages them in one bundle and a single installation. It also replaces the now-defunct GameSpy multiplayer systems with Steamworks features, enabling multiplayer to work without 3rd party software. Likewise, it also sorted out a number of software bugs.[7]

The company also announced that it will be developing and producing all-new flight simulation software based on Microsoft's genre-defining flight technology.[8] Following the announcement, the company announced on 25 July 2014 that it will be working in partnership with Flight One Software (Flight1), a developer and publisher of flight simulation content, to deliver a range of Flight1 add-ons for Microsoft Flight Simulator X: Steam Edition.[9] On 9 December 2014, Dovetail Games announced the launch date of Microsoft Flight Simulator X: Steam Edition would be 18 December 2014.[10]

On 4 August 2015, Dovetail Games announced plans with Microsoft to bring a number of its future releases to Windows 10 and Xbox One in 2016. The company said that Euro Fishing, currently available on PC through Steam, will be released on Xbox One. The next generation of the Train Simulator franchise, powered by Unreal Engine 4, will be released on both platforms and Dovetail Games Flight Simulator, built on the foundations of Microsoft's Flight technology, will be released on PC.[11] On 15 March 2016 Xbox announced that Flight School will be released on Windows 10.[12]

In September 2016, Dovetail Games announced Train Sim World, a new train simulator using Epic's Unreal Engine 4 and featuring the ability to walk around in the world. Train Sim World was later released in March 2017.[13]

In May 2017, Dovetail Games announced their new flight simulator, Flight Sim World, which released later that month.[14] However, a year after release, Dovetail Games announced it would stop development of Flight Sim World and remove it from sale in May 2018.[15]

In August 2020, Train Sim World 2 was released. While Dovetail Games was never able to deliver the promised multiplayer in the previous version, they say it is in their "future roadmap" and that Train Sim World 2 has "a design that we think will give a great social experience".[16]

Around the same time, the company launched We Are Railfans, an online rail community aiming to bring many aspects of railfanning to one place. By the end of 2021, hundreds of website articles on trainspotting, heritage rail, modelling and photography had been published to a growing community of over 35,000 Facebook users. The We Are Railfans Podcast supplemented this with detailed interviews from those within rail, including locomotive drivers, authors and TV personalities.[17]

On 28 October 2021, Dovetail Games released Bassmaster Fishing 2022 for PlayStation 5, PlayStation 4, Xbox Series X / S and Xbox One. It is an officially licensed game from the real world Bassmaster series of amateur and elite events. The game features 10 pro anglers including Scott Martin and Hank Cherry as well as 8 real world locations. A multiplayer mode is also featured.[18]

9 August 2022 saw the announcement of Train Sim World 3, for release on 6 September 2022 on PlayStation 5, PlayStation 4, Xbox, Steam and Epic Games Store. The announcement was preceded by a lengthy tease video which hinted at the various features to be included in the latest release, such as volumetric skies, a new dynamic weather system and the three new routes: Cajon Pass, Southeastern Highspeed (Extended) and Kassel-Würzburg.[19]

On 20 April 2023, Dovetail Games announced that they had been acquired by French video game developer Focus Entertainment in a mostly cash transaction. Full financial terms of the sale were not disclosed.[1]

In September 2023, Train Sim World 4 was released with brand-new features such as free roam, photo mode and formation designer.[20]

On 20 August 2024, Train Sim World 5, the eighth iteration of the series was announced and was released on 17 September, one year on from the release of Train Sim World 4. For existing users, the base game is a free upgrade, which was initially available for thirty days from the release date, but was extended to early 2025.[21]

The ninth iteration of the series, Train Sim World 6, was announced on 8 July 2025, and was released on 30 September.[22][23]

In 2025, Dovetail announced the rail-simulator racing game Metro Rivals: New York, and in 2026 a Thomas & Friends game, titled Thomas & Friends: Wonders of Sodor.[24][25] On April 15, 2026, Dovetail Games announced through their Metro Rivals Facebook page with a statement that they are ceasing development on the game.[26][27]

History

Founding and early development

Dovetail Games traces its origins to the development team behind the original Rail Simulator, a PC-based train simulation game created by Kuju Entertainment and released in Europe in October 2007 by Electronic Arts.[6] The project stemmed from Kuju's expertise in simulation software, including prior work on racing and flight titles, which informed the foundational physics and modeling systems used in Rail Simulator.[7] Following the game's launch, key members of the Kuju team, recognizing the untapped potential of the RailSim engine, acquired the intellectual property rights to continue development independently.[8] In 2008, the company was incorporated as Railsimulator.com Limited by Paul Jackson OBE, Charles McMicking, and Timothy Gatland, initially operating under the name Rail Simulator Developments Ltd (RSDL) to manage ongoing support and enhancements for the original title.[3] This new entity took over post-launch responsibilities from Electronic Arts, including the release of patches to address technical issues such as locomotive physics and route stability, while laying the groundwork for expanded content.[6] The founders brought complementary skills: Jackson's experience as former VP at Electronic Arts and director general of ELSPA (now UKIE), combined with McMicking and Gatland's technical backgrounds from the simulation sector, enabled a focused pivot toward enthusiast-driven rail software.[8] Early development centered on PC platforms, with the team prioritizing the refinement of a dedicated train simulation engine to improve realism in areas like dynamic weather, multi-player functionality, and modular add-ons.[9] This effort culminated in the June 2009 launch of RailWorks, the direct successor to Rail Simulator, which incorporated an upgraded engine to overcome initial limitations in graphical fidelity and scenario complexity while introducing a DLC model for routes and locomotives.[10] The small-scale operation faced typical startup hurdles, such as resource constraints in scaling the engine for broader compatibility, but established a foundation for iterative improvements in train simulation accuracy.[3]

Rebranding and expansion

Throughout the 2010s, RailSimulator.com Ltd, trading as the Train Simulator series, pursued significant expansion by developing and releasing over 200 add-ons and downloadable content packs, including licensed routes, locomotives, and seasonal updates that allowed players to customize and extend their simulations across global rail networks.[11] These efforts not only sustained annual updates to the core product but also fostered a robust third-party creator ecosystem, contributing to the series' longevity and commercial viability on PC platforms.[12] In December 2013, the company rebranded to Dovetail Games to encompass its growing ambitions in diverse simulation genres beyond rail, signaling a strategic pivot toward broader portfolio diversification while retaining its core expertise in realistic transport simulations.[1] This period of growth peaked with the 2017 launch of Train Sim World, a new flagship series built on Unreal Engine 4 that emphasized route-specific, first-person immersion and marked the company's entry into console markets, launching on PC before expanding to Xbox One in 2018 and PlayStation 4 thereafter.[3][13] The title represented a technological and experiential evolution, prioritizing high-fidelity recreations of real-world rail operations over the modular add-on model of its predecessor.[14]

Acquisition by Focus Entertainment

On April 20, 2023, Focus Entertainment announced the acquisition of 100% of Railsimulator.com Limited, the parent company of the Dovetail Games Group, along with its senior management team.[15][16] The transaction was completed immediately, with Dovetail Games consolidated into Focus Entertainment's accounts starting the same day.[15] Formerly known as Focus Home Interactive, the Paris-based publisher cited Dovetail's established portfolio in simulation gaming, particularly its expertise in developing intellectual properties like the Train Sim World series, as a key factor in the deal.[17] The acquisition was valued in a manner consistent with Focus's ongoing strategy, though specific terms were not disclosed; Dovetail reported over £15 million in revenue for the fiscal year ending March 31, 2023.[17] The strategic rationale emphasized Dovetail's alignment with Focus's focus on high-quality, niche genres and its potential for international growth.[15] Focus highlighted the UK developer's talented leadership and shared commitment to simulation enthusiasts, aiming to leverage its global publishing and distribution network—particularly in North America—to expand Dovetail's reach and explore new monetization avenues.[15][17] This move marked Focus's sixth acquisition, strengthening its portfolio in simulation titles amid a broader push into specialized gaming experiences.[18] Following the acquisition, Dovetail integrated into Focus's publishing ecosystem, benefiting from enhanced resources while retaining operational autonomy under its existing management.[15] A notable post-acquisition milestone was the release of Train Sim World 4 on September 26, 2023, for PC, PlayStation, and Xbox, which introduced new routes and features like an in-game editor, continuing the series' evolution under the new ownership structure.[19] In April 2024, Focus Entertainment rebranded as Pullup Entertainment. The series continued with Train Sim World 5, released on September 17, 2024, across PC, PlayStation, and Xbox platforms.[20] Train Sim World 6 followed on September 30, 2025, introducing further enhancements and routes.[21] In February 2025, Gemma Brown and Rob O’Farrell were appointed as co-CEOs, succeeding previous leadership and emphasizing innovation and diversity.[22] Ongoing development includes expansion into new simulation titles, with Pullup Entertainment supporting Dovetail's community engagement and market growth as of November 2025.

Products

Train simulation series

Dovetail Games' train simulation series began with the launch of RailWorks in 2009, marking the company's entry into the genre with a focus on realistic railway operations and hobbyist appeal.[11] This title evolved into Train Simulator Classic, receiving annual updates and editions such as Train Simulator 2016, which introduced enhanced graphics and expanded content libraries.[23] The series adopted a robust downloadable content (DLC) model, offering add-ons for diverse locomotives—from historic steam engines to modern high-speed trains—and routes spanning global rail networks, including the UK's Chatham Main Line and Germany's Konstanz to Villingen line.[11] By 2024, Train Simulator Classic featured over 300 DLC packs, enabling players to customize experiences with licensed rolling stock and scenery.[23] In 2017, Dovetail Games introduced Train Sim World (TSW) as a next-generation iteration, emphasizing console compatibility alongside PC while building on the foundational realism of its predecessor.[24] The inaugural TSW released on March 16, 2017, for PC via Steam, followed by expansions to Xbox and PlayStation. Subsequent versions iterated annually: TSW 2 in August 2020, adding a Scenario Designer for user-created missions; TSW 3 in September 2022, incorporating a Training Center and dynamic weather systems; TSW 4 in September 2023, introducing Free Roam mode for unstructured exploration; TSW 5 in September 2024, enhancing Conductor Mode and Live Map functionality; and TSW 6 on September 30, 2025, which integrated API support for external hardware and a comprehensive PC Editor.[21][25] These updates prioritized advanced physics simulation, including authentic train handling and environmental interactions, to deliver immersive scenarios like freight hauls and commuter services.[26] Key to the series' appeal are unique tools such as the Scenario Editor, available since TSW 2, allowing players to design custom timetables and challenges, and mod support via the Creators Club for liveries and formations across platforms.[24] TSW 6 expanded this with a PC-only Mod Manager and Unreal Engine-based editor for building routes and locomotives, fostering community-driven content.[26] Partnerships with rail operators ensure licensed authenticity, featuring routes like the UK's Riviera Line and Birmingham-Crewe, the US's Morristown Line with NJ TRANSIT and NEC New York-Stamford, and Europe's Bahnstrecke Leipzig-Dresden with Deutsche Bahn influences.[24][26] Collaborations with third-party developers, including Skyhook Games for UK content and TSG for German trains, further enrich the DLC ecosystem, which surpassed 100 add-ons by 2024.[26] The Train Sim World series is available on PC (Steam and Epic Games Store), Xbox, and PlayStation, with cross-ownership of DLC enabling seamless progression across editions.[25] This multi-platform approach, combined with regular free core updates in newer versions, has sustained a dedicated player base focused on realistic railroading.[26]

Fishing simulation series

Dovetail Games entered the fishing simulation genre with the release of Euro Fishing on November 2, 2015, for PC via Steam, marking the company's first venture beyond train simulations.[27] The game focused on European waterways, including renowned locations such as Chew Valley Lake in England and Chiemsee in Germany, emphasizing realistic fishing experiences through licensed equipment from brands like Korda and Shakespeare.[27] Key mechanics included precise rod handling, where players managed tension, casting, and reeling to mimic real angling techniques, alongside seasonal variations that influenced fish behavior and availability across different times of year.[28] Weather conditions, such as wind and rain, dynamically affected water clarity and fish positioning, adding layers of strategy to outings.[29] The series evolved with Fishing Sim World: Pro Tour, launched on September 18, 2018, for PlayStation 4, Xbox One, and PC, expanding the scope to global fishing destinations like Lake Travis in Texas and the River Trent in England.[30] This title introduced multiplayer support for up to four players (eight on PC), allowing competitive sessions with real-time leaderboards and customizable rules for rounds and match lengths.[31] Building on its predecessor, it incorporated over 50 licensed partners for tackle and boats, enabling extensive customization of gear to suit various fish species and environments.[30] Progression came via an in-depth career mode and mastery system, where players unlocked rewards by completing lake-specific challenges, fostering skill development across bass, carp, and predator fishing styles.[32] In 2021, Dovetail Games released Bassmaster Fishing 2022 on October 28 for PlayStation 4/5, Xbox One/Series X|S, PC, and Nintendo Switch, as an officially licensed product tied to the B.A.S.S. (Bass Anglers Sportsman Society) tournaments.[33] Players could select from 10 real Elite Series professional anglers, such as Scott Martin or Ott DeFoe, and compete in authentic events at eight U.S. venues like Lake Guntersville and the St. Johns River, recreating professional bass fishing circuits.[34] The game featured licensed gear from brands including Abu Garcia and Rapala, with mechanics simulating tournament strategies like lure selection and boat positioning during official B.A.S.S. events.[35] Across the series, core gameplay emphasized tackle customization, allowing players to assemble rods, reels, lines, and lures tailored to target species and conditions, enhancing realism and replayability.[28] Weather systems impacted simulations by altering fish activity—such as reduced bites in storms or heightened aggression in clear skies—requiring adaptive tactics.[31] Progression mechanics, including tackle points earned from catches and tournaments, unlocked advanced equipment and venues, while career paths simulated professional advancement unique to angling simulations.[32] These elements distinguished the series by prioritizing authentic leisure simulation over arcade-style action.[36]

Flight simulation titles

Dovetail Games entered the flight simulation market in 2014 with the release of Microsoft Flight Simulator X: Steam Edition on December 18, a port of the original 2006 Microsoft title developed by Aces Game Studio.[37] This edition updated the game for Steam platform compatibility, resolving issues with modern hardware and operating systems while incorporating additional aircraft models, scenery packs, and multiplayer features not available in the original boxed version.[38] The port maintained the core simulation of realistic flight physics, weather effects, and global navigation, attracting both longtime enthusiasts and new users through Steam's distribution and ongoing add-on support from third-party developers.[39] Building on this foundation, Dovetail Games launched Flight Sim World in Steam Early Access on May 18, 2017, positioning it as a next-generation flight simulator with a focus on modularity and accessibility.[40] Key features included a modular aircraft design system allowing customizable avionics and liveries, high-fidelity global scenery generated from satellite imagery, and an advanced weather engine powered by trueSKY technology that simulated dynamic cloud formations, volumetric fog, and haze for enhanced realism.[41] The simulator emphasized career progression through missions and training modules, integrating hardware support for joysticks and yokes while aiming to streamline add-on development via a unified ecosystem.[42] Despite initial promise, Flight Sim World faced significant challenges, including persistent technical bugs, performance issues on varied hardware, and difficulties in attracting third-party content creators due to restrictive digital distribution licensing agreements.[43] On April 23, 2018, Dovetail Games announced the discontinuation of all future development, citing unsustainable market conditions and the inability to deliver a polished product amid competition from established simulators.[44] The title was removed from sale on May 24, 2018, with existing owners retaining access but receiving no further updates or support.[45] The cancellation highlighted broader industry hurdles, such as the high development costs for photorealistic global environments and the timing just before Microsoft's announcement of Flight Simulator (2020), which overshadowed Dovetail's efforts.[46] Post-discontinuation, Flight Sim World saw no residual official support, and lessons from its technical and ecosystem shortcomings influenced Dovetail Games to refocus exclusively on rail and fishing simulations, avoiding further aviation projects.[41]

Urban transit simulations

In October 2025, Dovetail Games announced Metro Rivals: New York, an upcoming arcade-style multiplayer train racing game set in a near-future New York City subway system, slated for release in 2026 on PC, PlayStation 5, and Xbox Series X|S.[47] The title features competitive gameplay against AI "Track Titans" or players in PvP modes, emphasizing high-speed subway navigation, customization, and reputation-building across 10 dynamic tracks, diverging from the company's traditional realistic simulations to offer a more accessible "simcade" experience.[48]

Operations

Headquarters and workforce

Dovetail Games is headquartered in a river-front studio located in the Historic Dockyard, Chatham, Kent, ME4 4TZ, United Kingdom. This open-plan facility supports the company's development operations for simulation games, fostering a collaborative environment.[49][2] The company was founded in 2008 with a small initial team and has since expanded significantly, reaching over 60 staff by 2013 and continuing to grow through subsequent years. As of 2025, Dovetail Games employs over 140 individuals, primarily based in the UK, with roles spanning programming in C++ and Unreal Engine, 3D art for environments and assets, sound design including audio implementation, and quality assurance to identify bugs during development.[1][50][51][52][53][54] Following its acquisition in April 2023, Dovetail Games operates as a wholly owned subsidiary of PulluP Entertainment (formerly Focus Entertainment), a Paris-based publisher, while retaining its UK headquarters and leadership structure, including co-CEOs Gemma Brown and Rob O'Farrell appointed in 2025.[15][55][56] The company supports remote work opportunities within Great Britain but maintains its core workforce in Chatham without dedicated international offices.[56]

Dovetail Games fosters a vibrant community around its simulation titles, particularly through platforms like Dovetail Live, official forums, and Discord, where rail enthusiasts share user-generated content, industry news, and discuss upcoming events tied to Train Sim World.[57][58] The company actively supports modding in both Train Simulator Classic and Train Sim World, providing official tools to empower users in creating and customizing content. For Train Simulator Classic, Dovetail offers comprehensive developer documentation covering route, train, and scenery creation, along with licensing support for integrating add-ons into the ecosystem.[59] In Train Sim World, the Creators Club enables players to design and share liveries, scenarios, and train formations using built-in editors like the Livery Designer, Formation Designer, and Scenario Planner, with the PC Editor allowing advanced route and locomotive modifications.[24] These tools facilitate third-party integrations, such as SDKs for custom maps and locomotives in Train Sim World 2, allowing community developers to expand the game's content library.[60] Dovetail Games has established key partnerships with rail operators and brands to ensure authentic licensed content in its simulations. Collaborations with Amtrak provide official licensing for routes and locomotives, such as the Acela in the Northeast Corridor, enabling realistic recreations of U.S. passenger services.[61] Similarly, partnerships with UK rail entities support licensed routes featuring operators like Great Western Railway, while the fishing series benefits from an official tie-up with Bassmaster, incorporating Elite Series events, anglers, and tournament trails into Bassmaster Fishing titles.[62][63] To engage users and refine products, Dovetail hosts events like the annual Dovetail Direct livestreams, which reveal updates, roadmaps, and new content, often incorporating community input. The company runs beta testing programs where selected users provide early feedback on updates and features, helping shape development through structured playtests. User feedback mechanisms include dedicated forum sections for route and content discussions, as well as the official Discord server, where players submit suggestions that influence product roadmaps, such as enhancements to random events or licensing priorities.[64][65]
