London rails

Going down to London this last weekend i decided to indulge my love of rail travel and take advantage of my Oyster card with an orgy of local rail travel around the capital. Including tube, DLR, Overground and the trip down to London in the first place i managed 12 separate rail journeys in 1 day which wasn't bad going. I took a lot of photos of course. Highlights were the unexpected amount of freight i was able to see too, and Queen's Park depot which is unique on the London Underground in that in-service trains actually traval through the depot.
