For your enjoyment, some nice photos taken by Time Magazine of the London underground night time workers – and the work they do.

The Londonist and Annie Mole went down one evening and wrote about the night-time activities, which adds a level of detail to what the photos above are showing.

Is it me, or does Photo 3 in the Time article look a bit photoshopped?
