Europe is home to four of the 10 most expensive railroad projects. According to project cost, Railway Technology ranks the ten largest railway projects currently under construction worldwide.
1. $136 billion High Speed 2 (HS 2)
A new high-speed rail line called High Speed 2 (HS 2) is being built to link Scotland, the Midlands, and London. With 30 million users, the high-speed network will connect more than 25 stations. The project will be constructed in three stages and should be finished by 2035.
The 2015 Budget said that the first cost of HS 2 was expected to be $72 billion (£56 billion). The project’s anticipated funding has now increased by almost double, with the most recent investment rising to $136 billion (£106 billion).
The project is expected to reduce travel time from Birmingham to London from one hour and twenty-one minutes to fifty-two minutes, and from Manchester to London, Birmingham to Leeds, from two hours and seven minutes.
2. Chuo Shinkansen – $84bn
The Central Japan Railway Company is creating a new network of bullet trains called the Chuo Shinkansen, commonly referred to as the Tokaido Shinkansen Bypass (JR Central). The planned Maglev-based route between Tokyo and Nagoya is expected to cost $84 billion (9 trillion).
The new line is expected to travel at a top speed of 500 km/h and connect Tokyo and Nagoya in 40 minutes. Ninety percent of the 286 km long route will be tunneled.
3. California High-Speed Rail – $80bn
The Central Valley in the United States will serve as the connection between Northern and Southern California for the publicly sponsored high-speed rail route known as the California High-Speed Rail. The California High-Speed Rail Authority is building the 1,300km-long high-speed rail network at an estimated cost of $80 billion.
The California high-speed rail project was officially launched in January 2015, and it is expected to be finished in 2040. It is being developed as the country’s first high-speed rail system.
4. Northern Powerhouse Rail (NPR) – $47bn
A new rail network called Northern Powerhouse Train (NPR) is being built in the North of England to increase rail capacity. The NPR is expected to cost $47 billion (£39 billion), making it the greatest transportation project to be undertaken in the area since the Industrial Revolution.
The creation of the NPR program is the responsibility of Transport for the North.
5. Suburban Rail Loop – $34bn
The Suburban Rail Loop Authority is creating an orbiting train system called the Suburban Rail Loop (SLRA). The project will go around Melbourne and connect the city’s main railway lines through Melbourne Airport.
The anticipated cost of the Suburban Rail Loop project is A$50 billion ($34 billion). Construction on the first stage (south-east segment) of the 90km-long railway network is anticipated to begin in 2022 with a target completion date of 2032.
6. Grand Paris Express – $31bn
In France’s Ile-de-France, the Grand Paris Express automated transport network is currently being built. Grand Paris Express is one of the greatest transit projects presently being developed in Europe and is expected to cost $31 billion (€28 billion).
The project entails the development of 68 new stations as well as four new railway lines. The 200km-long new railway network will have 90% of its construction underground. Beginning in June 2016, construction is anticipated to continue until 2030.
7. London Cross rail Project – $24bn
The central London, UK, railroad project known as Crossrail is 118.5 kilometers long. The Elizabeth line, a brand-new railroad, will run at high frequencies between Shenfield and Abbey Wood in the east and Reading and Heathrow in the west, stopping at 41 stops in all.
The Crossrail route consists of three portions, namely the western, central, and eastern, and is expected to cost $24 billion (£18.7 billion). In the first half of 2022, the Elizabeth line started accepting passengers.
8. Riyadh Metro – $22.5bn
As part of the Riyadh Public Transport Project, the fast transit system known as Riyadh Metro is being built (RPTP). The project, which is expected to cost $22.5 billion, is Saudi Arabia’s largest public transportation undertaking.
In this project, six major lines with a combined length of 176 km and 85 stops will be built. The majority of the densely inhabited areas, together with government, educational, and commercial institutions, are traversed by the Riyadh Metro network.
9. Mumbai-Ahmedabad High-Speed Railway Corridor – $15bn
The National High-Speed Train Corporation Limited (NHSRCL) is building a high-speed rail line to connect Ahmedabad with Mumbai, the country’s financial center. It is India’s first high-speed rail project currently in development.
The project, which is expected to cost $15 billion (Rs1.1 trillion), is supported financially and technically by the government of Japan. In order to complete the high-speed rail line, 12 stations and a 508km long railway network must be built.
With the elevated track, high-speed trains will be able to travel at 320 km/h, and the limited-stop service will take two hours to complete the route. In the Mumbai-Ahmedabad High-Speed Rail Corridor, 36,000 passengers would be able to travel each hour.
10. Klang Valley Mass Rapid Transit Project – $12.2bn
A 150km Mass Rapid Transit (MRT) system is being built in Kuala Lumpur as part of the Klang Valley Mass Rapid Transit project. Two northeast-southwest radial lines, as well as a circular line that round the city, will be part of the system.
The Greater Kuala Lumpur/Klang Valley National Key Economic Areas of the Economic Transformation Programme identify the $12.2 billion (MYR50 billion) project as an Entry Point Project (EPP) (NKEA).
The 23 km long MRT Kajang Line between Sungai Buloh and Semantan’s first phase was finished in 2016. In 2017, the MRT system’s second phase between Sematan and Kajang was finished. In 2023, the third and last line is anticipated to be operational.
