Alphabetical thing: Brockley

Brockley railway station is on the Southern route from London Bridge to Croydon. A footbridge links the two platforms, and another bridge carries the SouthEastern line from Nunhead to Lewisham directly over the station, although it doesn't stop there.

What's outside the station? What looks like a clockwork-powered house. However, this isn't really a cunning way to cut carbon footprints, but just a trompe-l'œil mural.
