First rail milling train in UK to be used in Crossrail maintenance

The first rail milling train in the UK will be used to support Crossrail developments after Linsinger won a £12m contract.

The model MG31 train will be delivered in spring 2018 and will be located at the Plumstead infrastructure maintenance depot in south east London.

It will support maintenance in the Crossrail tunnels by restoring rail head geometry in order to reduce long-term wear of rails and wheels.

The train is 48m long, with a maximum axle load of 20 tonnes. It can travel at 80kmph and mill at 3m every minute.

It features a 12 cylinder, 4 stroke diesel engine with 1125 bhp, CBTC signalling to allow operational hours running between sites, and a suction system to ensure that milling chips or grinding dust are not left on the track and is built for low greenhouse gas emissions.

Silly Question here ! As the whole of the Crossrail route is electrified with overhead wires, with a considerable amount of the route in new tunnels Why is there not the option to have this machine electrically powered ? Surely emitting exhaust into a tunnel environment is to be avoided in this billion pound electric railway, once it is up and running !

If it goes successful then it could also be used for the Crossrail 2 project.

Scottie, the traction current will often be switched off for maintenance.

The milling speed is up to 30m/min

Despite a few disappointing policy announcements, especially for the electrification aficionados amongst us, 2017 was, like Darren Caplan writes on page 20, a year generally marked by positive news for the rail industry. We polished off the iconic Ordsall Chord (p32), hit some solid milestones on Thameslink (p40), progressed on ambitious rolling stock orders (p16), and finally started moving forward on HS2 (p14) ‒ paving the way for a New Ye... read more >
