Definitely a train set not a model railway. Here are some in-progress pics taken in the last couple of days:
Hopefully you can see the size of the thing and also gauge roughly how its intended to work. Some fiddling and fettling of lines is still needed, one or two have been knocked out of straight while doing other jobs, but they seem to fiddle back OK.
Today I've been doing the section from the end of the trundleduct distant from the station, and taking the concealed back straight round to meet the trundleduct; it will go behind a backscene that is mounted on the trundleduct.
I am beginning to feel it might one day be finished (or at least playable). It's a way off yet, but do people usually have a "golden track pin" ceremony?
