Crossrail awards contract for rail milling train

Crossrail Limited has awarded a contract for a rail milling train (model MG31) to Linsinger – the value of the plant contract is in the region of £12m.

The vehicle will support future rail maintenance within the Crossrail tunnels. The rail milling train reduces long-term wear of rails and wheels by restoring rail head geometry.

The rail milling train will be delivered in spring 2018 and will be located at the Plumstead infrastructure maintenance depot in southeast London. The rail milling train will be the first of its kind in the UK.

A low emission engine facilitates operation in tunnels while the suction system ensures that milling chips or grinding dust are not left on the track.

The rail milling train can travel at up to 50 mph (80 km/h) between worksites and will be installed with CBTC signalling to allow operational hours running between sites.

The MG31 milling train is 48 metres long and with a maximum axle load of 20 tonnes. The engine is 12 cylinder, 4 stroke diesel engine with 1125 bhp. Milling speed is 3 metres per minute.
