If you want a good starting point for local tram information, then I can recommend
South London Tramways 1933-52, by Robert J Harley, published by Middleton Press 2006,
ISBN 1 90447489 6.
I spotted this in WHS Catford, which used to have a special section on trains, trams, buses etc.

A tram that ran through Forest Hill from Victoria to Lewisham and then to the southern end of the Blackwall Tunnel, was the no. 58.
The same route (apart from the Blackwall Tunnel bit) is used by the 185 bus. Apparently it was policy to use the old tram number so that passengers could understand the new bus routes, so 58 tram became 185 bus.
Not sure about what happened to the 62, the 35 or the 66 which all went through or started at Forest Hill in 1934, according to the map in the book.

I am not a tram fan, but I remember going on a tram during the "Last Tram Week" which was in July 1952, I believe.
