Thank you,
I only know it from photos aswell , it had gone long before i was born !
That is intresting about the halls and the 66xx at Slough. I never knew there was one shedded there. I have a copy of the Great Western Journal and there is some superb photos in it. We have used them alot for building this. There is another issue aswell ( i cant remeber which one though ) that has a lovely double page spread of a Dukedog going over the level crossing.
Thanks for the info and the links, they are gonna be a great help.
