Stadler Euro Dual
The Stadler EuroDual (known as the Vossloh Euro Dual until 2015) is a series of dual power, electro-diesel locomotive by Stadler Rail Valencia. Unlike traditional dual mode locomotives, fitted with relatively low-powered diesel engines for 'last mile' movements only, vehicles are typically furnished with power units more comparable to that of mainline diesel locomotives.
The EuroDual series was launched by Vossloh during 2012. It shares a considerably large portion of its design with the single power Eurolight family of locomotives. Being customisable to meet customer demands, various sized powerplants can be fitted to the type; it can also be configured as a tri-mode vehicle via the installation of a battery pack. To date, there are three distinct versions of the EuroDual that have seen customer use; the UKDual for the United Kingdom, the PrasaDual for South Africa and an unbranded series for Germany. By late 2019, a total of 30 locomotives had been constructed, while a total of 74 Euro Duals were reportedly on the company's books.
At Innotrans 2012, Vossloh announced the launch of its range of dual mode locomotives; the company's initial offerings included the Vossloh DM30 concept based on the Vossloh DE 18, and the EuroDual locomotives derived from its diesel Euro 4000 and EuroLight classes. Specifically, the Euro Dual shares the majority of its design, including elements such as the bodyshell, braking systems, bogies, traction equipment and software, with the Eurolight series. Initial descriptions issued by Vossloh were of a Co'Co' locomotive with 5 MW electrical power and 0.7 to 2.8 MW (940 to 3,750 hp) diesel power, with an axle load from 17 to 22.5 t (16.7 to 22.1 long tons; 18.7 to 24.8 short tons). Subsequent orders differed from the initial specifications, with orders from the UK and South Africa being for Bo-Bo locomotives. At Innotrans 2018, the new Eurodual was presented by Stadler; the first two versions are marketed as UKDual and PrasaDual, while a third variant of the EuroDual featured the Co-Co wheel arrangement.
In comparison to historic dual mode locomotives, the Euro Dual series was not designed with a low-powered diesel powerplant intended only for 'last mile' operations with restrictive acceleration, speed, and range; rather, it was a full capable locomotive in either diesel or electric modes. It has been designed for routinely handling heavy freight consists, the series is reportedly expected to function as a dual-mode replacement for the successful Euro 4000, which will soon cease production as the latter is not compliant with European Stage IIIA emission standards. The Euro Dual is suitable for both passenger and freight applications, being able to operate at speeds of up to 160 km/h (99 mph). The market for dual mode trains is seen to be a growing one in comparison to conventional single mode diesel locomotives; by 2019, relatively few pure diesel locomotives were reportedly achieving sales.
The Euro Dual was designed from the onset as a highly modular platform, allowing it to be offered to customers in various different configurations, covering various gauges and voltage systems. Accordingly, it can be equipped with diesel engines of various power ratings, being determined by the requirements of each specific customer. Despite this customisability, many features such as the bodyshell are capable of accommodating such range with little meaningful modifications. Furthermore, some versions of the Euro Dual series are tri modes, which are capable of being powered by either overhead electrification, a diesel engine, or an array of batteries. When fitted with a battery unit, the starting power of the locomotive can be augmented beyond conventional limits, enabling trains to accelerate faster by augmenting the starting tractive effort of the diesel engine to around 500 kN. Another advantage of such a configuration is the ability to recover energy via regenerative braking, improving operational efficiency.
In September 2013, UK rail operator Direct Rail Services announced it had ordered ten Euro Dual locomotives, with a 700 kW (940 hp) engine, and 4 MW rating electrical equipment (25 kV AC operation). The type was subsequently designated as the Class 88. The design is a development of the Class 68 (Stadler UKLight) diesel locomotives that Direct Rail Services introduced in 2014, having the bodyshell, cab, brakes, bogies, traction equipment and control software in common, the diesel engine is a 950 hp (710 kW) Caterpillar C27, albeit a model that conforms with the European IIIB emissions standards unlike that of the Class 68.
In April 2016, one vehicle was transferred to the Velim railway test circuit for testing.
In January 2021, Rail Operations Group confirmed their order of 30 Class 93 locomotives, with the first ten deliveries scheduled for 2023. Unlike the earlier Class 88, these shall be tri mode vehicles furnished with a battery pack, enabling operations away from overhead catenary wires without activating the diesel engine.
