I was born in 1942 and lived close to the GWR /BRW mainline just south of Tyseley. An uncle was a driver there so got some unofficial visits.
In those days kids were allowed much more freedom to wander about than would be allowed now, so i often went to 'watch the trains'. When about 10 I was allowed to catch the train to snowhill on a saturday morning and by about 13 I was going on various excursions all over the country - it developed an indepence I am glad I got/have.
Occassionally on the saturday trips I would cross over to Newstreet but the old station seemed dirty and confirmed GWR was best!
Obviously then engines must have copper topped chimneys!
