2ft is quite high, to me this is important which means that photography, even when looking up at the colliery buildings you'll still see the backscene behind the layout rather than room the layout is in.
This combined with bright even neutral illumination (yet to be decided, but it won't be spots which are dreadful!! LED might be an option btw.) should give a good airy spacious feel which hopefully will disguise the 4 x 2ft footprint and fool people into thinking the layout is much bigger.
Deadline, end of May at Railex!
Polbrook Gurney Colliery will shortly be featured in far greater detail in Model Rail magazine.
