I was at West Kensington when a battery loco hauled engineer's train passed through heading west. I jumped on the District Line service
that was following it, changed to the Piccadilly at Barons Court, and hoped that the train I was on would overtake the engineer's train.
My train caught the engineer's train at Acton Town, and I ran out of the station and onto the road bridge to record the battery locos as
they departed with the Piccadilly Line service that I had just alighted from alongside. L22 is the rear loco on train 646, a spoil train that
had come from an engineering possession at Aldgate and was heading back to Ruislip Depot.
