I like this idea and Ring Road - mainly because they are the railway running through a typical slice of 'modern' Britain. Bits of the old railway, bits of new, all wrapped in scenes we take for granted.

PS i generally despair at modern image layouts due to the lack of imagination typically shown by the builders... straight track on flat boards running parallel to the layout front or a minimum space TMD - how many like this have we all seen? So on that basis - very well done!

For inspiration also have a look at the approach to Tamworth low level from the Stafford direction.....
