Hi Mike.
I've spend the last few nights, once the engineers' T3 possession's have went on, reading through the thread for your layout and I have to say what you have achieved is truly commendable.
The level of detail with the scenic side of things and the traffic side are superb.
That's the good thing about the S&C. Right the way through from the steam era, 50's and 60's, BR Blue, Sectorisation to the current privatised nonsense the infrastructure hasn't really changed so in that regard is timeless!
It's given me the inspiration to push on with my own S&C layout based on a location further north - Long Meg Sidings. It's not going to be an exact replica but loosely based upon the Sidings. And set firmly in the diesel era!
A recent house move means I have a ready fitted out loft conversion to use to house it. (Cleaner and warmer than the loft in the previous flat we lived in though a much smaller area.)
I will have to use a helix at each end to gain access to the fiddle yards, though having read your trials with them I might have to restrict my train lengths, but on the otherhand having read the thread for Everard Junction, the helii (plural of helix?) on that layout seemed to work alright.
Anyway, keep the pictures coming please!
Cheers
Dave.
