Need some help concerning trains
I'm writing a story and one particular aspect of the story is that it involves one of the characters taking the train to his place of employment everyday. The story is set in 1930's England but one thing that I'm totally unfamiliar and ignorant with are trains in the aspects of which train on the station leads to where and all that. As I read Agatha Christie's books she so clearly understands it because for one she took trains and two, she lived in England and I haven't experienced trains or even went to London, nevermind talking about living there! Can anyone help me if they could? I know I haven't said much to go out on but some help would sure be great I've been trying to do some research but so far, no good. Thanks!
