Tata Steel has won an order to produce 60kt of high-quality rail for a new high-speed line linking the two holy cities of Mecca and Medina in Saudi Arabia.

The new railway will allow millions of pilgrims to cross the 276 miles (444km) between the two cities at speeds of 200mph (320kmh). The line will cross desert, withstanding temperatures ranging from freezing to 50ºC, as well as sand storms, flash flooding and shifting dunes.

Steel for the project will be made at Tata Steel’s Scunthorpe plant before being rolled into rail in lengths of 25 metres both there and at the company’s plant in Hayange, Northern France.

Work on producing the rail will start at the end of this year and is expected to continue throughout 2014.

Tata Steel rail has already been used successfully in similarly challenging conditions for projects in Brazil and Mauritania.

Last year the Saudi Railways Organization awarded the contract for the final phase of completing, running and maintaining the Haramain High-Speed Rail Project to a group of Spanish infrastructure, construction and technology companies.

The new line is expected to carry around 160000 people a day — and even more during the Hajj pilgrimage. They will be transported on a fleet of 35 new high-speed trains.

The project started in 2009, with an estimated cost of more than €12bn. The new rail line is set to open to the public in late 2014 or early 2015.

Besides the two holy cities, the line will have three other stops, two in Jeddah for commuters and one in Saudi Arabia’s new King Abdullah Economic City, a residential, industrial and commercial macro-complex that is still being built.

Spanish construction companies Copasa, Imathia and OHL are responsible for building the line’s superstructure and the track bases, as well as for the line’s mechanisms.
