L410 (51345, 59497 & 51387) runs along the down relief line at Langley on 6 November 1986 with the 2F42 14:03 Paddington to Maidenhead Network SouthEast service. It has just called at Langley station, which can be seen in the background. The large building on the right is Clare House, a large brick built office building, which the letting agent says was constricted in 1989. It looks pretty solid in this 1986 view!
