L29 passes through Harrow-on-the-Hill with train 640, a Farringdon to Ruislip Depot engineer's train as a Baker Street Metropolitan
Line service departs. The sky is genuine, although the S Stock was actually stood in the platform when L29 rolled through, so I took a
a head on shot, then took another from the same spot as the S Stock departed and stitched the two together. Not the shot I had planned
but I'm happy with the recovery.
