Russian steel company Evraz has delivered the first batch of 100m head-hardened R65 DT-350 rails to Russian Railways.
The move forms a part of the modernisation project by the Evraz rail and beam mill, which has seen an investment of roughly RUB18bn ($514.31m).
The mill currently has the capacity to manufacture approximately 950,000t of rail products every year.
The trains will be operated by Oktyabrskaya Railway, which comprises the railway infrastructure of the north and west of Russia, as well as the high-speed railways connecting Saint-Petersburg and Moscow.
Evraz railway products division head and vice president Ilya Shirokobrod said: "This is another high technology product added to Evraz’s portfolio that complies with advanced quality standards. Not only will it help us reinforce our home market positions, but also to discover new export opportunities."
The company also plans to improve DT350CC rails, in order to make them suitable for high-speed traffic lines with speeds of up to 350km/h-400km/h by the end of this year.
The company has secured the licence to produce head-hardened rails in November 2013.
