Better get used to hearing about it: the London Underground turns 150 next year, and there is a grand number of projects commemorating the anniversary. One of the longest-gestating is Met 353, the restoration of a Metropolitan Railway carriage from 1892. Throughout 2013 it'll be pushed and pulled around various bits of railway (including a steam-driven ride along the oldest section of the network).
In the video above, Met 353 is put through its paces in Loughborough (that's the town in Leicestershire, not the Junction). You can follow the progress on the London Transport Museum blog.
