Two thirds of set L831 (53265 & 59115) & Class 121 'Bubble Car' 55030 (L130) approach Iver on 22 February 1990 with the 2A40 11:01 Maidenhead to Paddington Network SouthEast service. Although I have quite a few pictures of a Class 121 replacing the DMBS vehicle of a Class 117 set, I have far fewer pictures of this 121/101 combination.
