Custom House to North Woolwich reused

The closed eastern extremity of the North London Line has been rebranded the Royal Docks Heritage Railway. The line will also be run as a rail training school, and a fancy diesel thingy is being transferred there from Swindon for this purpose. There's even talk of redoubling the tracks, using one for heritage trains and one for driver training.

The whole project has a wonderful air of doomedness, since if Crossrail goes ahead it will all be obliterated.
