Crossrail West Outers – track drainage works

Track drainage replacement project for Crossrail (on behalf of Balfour Beatty Rail / Lanes Group PLC)


We worked for Lanes Group Rail Division to complete a project replacing track drainage on the western section of Crossrail. The £14.8 billion Crossrail programme involves the construction of a new 73-mile east-west route from Maidenhead in Berkshire, through central London to Shenfield in Essex.

We were commissioned to replace track drainage along a section of line being lowered to allow new overhead power lines to run under a bridge. These overhead power lines are being installed as part of the Great Western electrification programme.


The work involved removal of 200 metres of track drainage and replacing it with new pipework as part of work to upgrade lines incorporated in the Crossrail programme.

The Rail team completed the track drainage renewal near Slough in Berkshire, over two consecutive weekends.


The track drainage renewal project was completed in two stages. During a track possession on the first weekend, the Rail team removed the previous drainage and system.

Then, the following weekend, the new track drainage was installed, along with new catch pits.

On both weekends, a total of 16 track drainage skilled operatives, plus supervision and site engineers worked on the project, in four 12-hour shifts throughout Saturday and Sunday.


The successful completion of this project, on behalf of Lanes Group PLC, demonstrates Pro Rail’s competency in carrying out track drainage renewal on Network Rail assets.

All site works were completed to programmes budget, quality and environmental targets with zero accidents on site.
