COP Stock Cab at Quainton
London Underground Surface CP/CO Stock
Just to confirm the previous page we have found an illustration of "CP" stock departing from Amersham station in the early 1960's which confirms the electrification had arrived before the "A" stock were fully ready to take over the services. (The type listings for CP/CO stock are quite complicated and derived from the original "O" and "P" designation but amended after later modifications to these units.)
A couple of other images further below may interest QRS members as they involve a Metropolitan car now resident at Quainton and under restoration.
