Brian, Hoover,
Ranger, thanks.
The two buildings for the backscene are old pics , one is copied from a black and white postcard I came across - i think the building was in Leeds, and the other a pic from the web that the owner allowed me to use.
Since building this I have become a big advocate of small layouts - They can be LOTS of fun! Most importantly the end of the build is quickly in sight and so keeps momentum high.
