The first time I went to Snow Hill was when I was about 5 y.o. in the mid 'fifties.My parents used to visit my grandparents who lived in Shropshire,so we used to catch the Paddington-Birkenhead express on platform 5/6.
The trains from London used to thunder out of Snow Hill tunnel,usually headed by a 'King' or 'Castle' class loco,and they used to frighten the daylights out me at first!After I realised that these great locos weren't actually harmful to young boys,I really used to enjoy my trips from Snow Hill.
Later,in the early '60s I went trainspotting there quite often.There were times when the station wasn't so busy,which was a good time to explore.One afternoon a friend and I went round onto Platform 1,climbed on one of the platform benches so we could have a look through the windows into the new signalling control room,which dated from 1960.This was like looking into 'Mission Control Houston' as the signal control panel was the latest in technology at that time.Either side of the panel were some very old looking wooden telegraph instruments (train describers) which looked really out of place along side the shiny new panel.
Later,when I was studying at Aston University (when the only train to use the station was known as 'The Bubble') I would sometimes walk over to Snow Hill at lunchtimes.It was quite derelict by them,and I'd have a look round at the vandalised remains-but the memories were still there.
