Tickets for the ever-popular tours of Aldwych tube station are on sale again. Trips round the station, which was closed in 1994 (these days it's mainly used for TV and film shooting), will take place Thursdays to Sundays between 22 January and 15 February 2015 and will cost £25/£20.
You'll get to nosy round the ticket hall, lifts, platforms and walkways, and there's 50% off admission to the excellent London Transport Museum included in the price. Be aware that there are 160 steps to get down to platform level — and, more pertinently, to get out again.
If you'd rather think of Aldwych back when it was a working station, take a look at this video that we shared a couple of years ago.
