nhy581: Thank you so much for the comments, as well as everybody else I might not have mentioned! I'm still gobsmacked by all these comments I couldn't have imagined getting among all the great modelling one can find on this site. I'll try to keep this thread updated - whenever I have actually time to get on with the project.
A good note from NGT6 1315, the track is actually standard Peco Code75. I have considered trying to build a layout with the correct 17.5 mm gauge but never seen it worth the effort really. On the other hand I've been thinking of building something in the 0 scale and with that I calculated that by choosing the scale 1:48 and using the standard 32 mm gauge track it is pretty much exactly correct. But with H0, mea culpa!
Caradoc: wonderful anecdote! Just like certain unreliable trains today; you sit in it for ages and the name of the station stays the same! Your story reminds me of the Soviet Union passenger coaches, one of them had a huge text PECTOPAH on the side and as a kid I was wondering who is so important he has his name on the coach like that.
Allegheny1600: Unusuality is all in the perspective - if I'll one day do something really exotic to me, I'll build a GWR branch line layout (which I'd love to do actually, being a huge fan of railways of Britain). :-)
