The Mecca Metro or Makkah Metro is a metro system with four planned lines in the city of Mecca, Saudi Arabia. The Metro was constructed by China Railway Construction Corporation[3] and is run by Mecca Mass Rail Transit Company (MMRTC). The metro forms part of the 62-billion-riyal Mecca Public Transport Programme (MPTP), which will include integrated bus services.[1][4][5]

The four proposed metro lines[5] will be in addition to the existing Al Mashaer Al Mugaddassah Metro line: 18.1 km, connecting Mecca, Arafat, Muzdalifa, and Mina opened in November 2010.[6][7]

Many people utilize the Mecca Metro during the Hajj. The price for the metro is 250 riyals, with prices lowering to 100 riyals if traveling on the last day of Hajj.[8]

Planning

[edit]

In August 2012, it was announced that the Saudi government had approved a US$16.5 billion budget to build four metro lines (182 kilometers (113 mi)) of the system.[9] The announcement gave an estimated time period to completion of 10 years. Invitations for tenders were due to be issued in January 2013.[10]

Four new lines are to be built.[11]

  • Line  A  : will connect Mecca to large multilevel parking facilities from the south to the northeast.
  • Line  B  : is a straight link between Mina and Mecca and continues parallel to the HHSR into the southwest.
  • Line  C  : will connect Arafat and Mina to the west side of Mecca and continues to the northwest.
  • Line  D  : will connect the south to Mecca with a straight extension to the west.[12]

Work on the 188-kilometer (117 mi) long metro network with 87 new stations had been expected to commence construction in 2015,[1] then in 2016,[2] but had not started ever since. After a failed tender in 2017,[13] the Saudi government restarted the project in summer 2024 by ordering a feasibility study on phase 1 of the project. This phase with a US$8 billion budget covers planned line B and most parts of line C, while line A will be in the second phase, and line D plus a northern extension of line C will be part of phase 3.[12]

MMRTC has appointed Prasarana Malaysia to provide consultancy services during Phase 1, which covers the construction of two metro lines, totaling 45.1 km and 22 stations by 2019.[4][needs update]

The Mecca Metro, also known as the Makkah Metro, is a system in , , comprising an operational shuttle line for pilgrims and planned urban lines to support both religious and daily mobility needs. The Al Mashaaer Al Mugaddassah Metro Line, its currently functional component, spans 18.1 kilometers with nine stations connecting the holy sites of Mina, Arafat, and , and holds the as the highest-capacity metro line globally, with a throughput of 72,000 passengers per hour per direction. A larger network of four lines totaling approximately 182 kilometers is under development to integrate the city center with surrounding areas, including new urban developments. The Al Mashaaer Al Mugaddassah Metro Line was constructed by the under a $1.8 billion contract awarded in February 2009, with the first phase opening on , 2010, and full operations commencing in November 2011. Managed by the Makkah Mass Rail Transit Company, the line operates exclusively during the annual pilgrimage, typically for 7 to 10 days, to alleviate road congestion and transport up to 500,000 pilgrims daily across its elevated tracks. It features 12-car trains manufactured by Changchun Railway Vehicles, each carrying over 5,000 passengers, and during the 2025 Hajj, it completed 2,154 trips while safely moving 1.87 million passengers with zero incidents under extreme conditions of 50°C heat and high winds. Fares for Hajj access are set at 250 Saudi riyals for most days and 100 riyals on the final day, with services running in coordinated patterns aligned to pilgrimage rituals. The broader Mecca Metro project originated from feasibility studies initiated in 2010 by , with preliminary designs for urban lines completed between 2013 and 2015, envisioning a public-private partnership structure. Ownership was transferred to the Royal Commission for Makkah City and Holy Sites, and in June 2024, the $8 billion first phase feasibility study was restarted by , supported by and Watson Farley & Williams, marking renewed momentum for the 182-kilometer expansion. In September 2025, the Royal Commission began engaging contractors for the first phase. This development aims to create a comprehensive network with Lines A, B, C, and D, enhancing connectivity for Mecca's population of approximately 2.2 million (as of 2025) and accommodating projected increases in pilgrims to 5 million annually.

History and Planning

Inception and Initial Approval

The Mecca Metro project originated in the early as part of Saudi Arabia's broader urban transport initiatives aimed at alleviating congestion and managing the influx of millions of pilgrims during the annual and seasons. These efforts sought to modernize infrastructure in the holy city to support sustainable growth and enhance mobility for residents and visitors alike. Initial concepts focused on developing a comprehensive rail network to complement existing systems strained by peak-period crowds exceeding 3 million people. Feasibility studies for the core metro system commenced in 2010, led by French engineering firm , which evaluated routes, capacity needs, and integration with the recently operational Al Mashaaer Al Mugaddassah Metro line—a 18.1 km elevated network connecting Mina, Arafat, and that had begun service in November 2010 to transport up to 72,000 pilgrims per hour during . The studies emphasized seamless operational coordination between the new urban lines and the pilgrim-focused Al Mashaaer line to optimize pilgrim flows without physical interconnection. Early planning outlined a four-line network spanning approximately 182 km with 88 stations, designed to serve daily commuters while scaling for seasonal demands. In August 2012, the Saudi Cabinet formally approved the project, allocating 62 billion Saudi riyals (about US$16.5 billion) for the development of the four-line system under the Mecca Mass Rail Transit Company. The approved routes included Line A running from the south (Al Sail area) to the northeast toward , facilitating access to peripheral parking hubs; Line B providing a direct east-west link from Mina to central ; Line C extending from Arafat and Mina to the west and northwest districts; and Line D connecting southern suburbs to western areas, including key interchanges near the Grand Mosque. Tenders issued that year aimed to select constructors leveraging experience from the Al Mashaaer line, but awards were delayed due to subsequent financial reviews.

Delays and Project Revivals

In , the Mecca Metro project encountered major delays as authorities restructured its US$16.5 billion financing amid sharp oil price fluctuations and ensuing budget constraints that strained Saudi Arabia's public spending. The decline in global oil prices over the prior two years had created a significant fiscal deficit, leading to cutbacks in infrastructure initiatives and modifications to the project's design, such as scaled-down metro stations near the Grand to control costs. Although an initial announcement by the project's CEO highlighted these issues, it was later retracted amid confusion, but the restructuring effectively postponed progress on the 182 km network planned across six phases. Tender processes for key contracts faced further hurdles in , resulting in the suspension of awards originally anticipated as early as January 2013 following the project's 2012 approval. Deals worth approximately $5 billion for Phase 1, including track and station development, missed their May deadline and were deferred to later in the year, with major bids from firms like Nesma & Partners and remaining unresolved due to ongoing financial reviews. This suspension stalled on-site activities and contributed to broader project inertia. From 2018 to 2020, the initiative saw limited advancement through periodic internal reviews, including partial explorations of integration with the for enhanced pilgrim connectivity, though these efforts yielded no substantial breakthroughs amid persistent budgetary pressures. The intensified these challenges between 2020 and 2022, disrupting transport infrastructure planning in and complicating preparations for high-volume pilgrim movements during and seasons. By 2022, costs had been adjusted to around 62 billion Saudi riyals via a more modular phased implementation to align with fiscal realities.

Recent Developments

In summer 2024, the Mecca Metro project resumed its Phase 1 feasibility study after a 14-year hiatus stemming from earlier delays, including a suspension in 2016. This phase centers on Lines B and C, encompassing 45.1 km of track with 22 stations at an estimated cost of US$8 billion. Prequalification for contractors was opened in early 2025 to invite bids for civil construction works on Phase 1, with an introductory meeting for interested firms held on September 21, 2025. China Railway Construction Corporation reaffirmed its involvement in the project, building on its prior experience with rail infrastructure in the region. Updated timelines indicate that construction is targeted to begin after 2025, with Phase 1 operations commencing by 2032 as part of a three-phase rollout extending to 2045. On November 19, 2025, signed a (MoU) with the Royal Commission for Makkah City and Holy Sites to participate in the King Salman Gate development, focusing on high-density precincts and seamless mobility integration. As of November 2025, the feasibility study remains ongoing with no groundbreaking achieved, though the project aligns closely with objectives for sustainable urban mobility and pilgrimage facilitation.
