Replying to the three responses to my query:-
Thanks guys, your help is appreciated.
l will investigate the film mentioned it sounds promising.
I was aware of the book on the Slough Industrial railway, but thought that its area was too far west to help me. So now I will investigate that further!
I had not yet got to considering signals so the signal pics will be useful in the future.
Because I want to run my layout with modern stock as well as 1960-2, I am omitting the middle bay (which was little used by 1962) and connecting the Windsor branch only into the fast lines.
I will have to make my engine shed removable and have a car park plate that sits over the engine shed sidings for the modern version.
While I have anumber of piucs of the engine shed, I don't have any details for the turntable or coaling stage, so any thoughts on that area would be welcome!
Best regards
Paul
