I went to see Pete Waterman's, O gauge, Leamington Spa layout recently, I found that certainly is inspirational.
The as yet, unpainted resin bridges, are covered in rivets, and really finely detailed, with different size girder spans on the same bridge.
A green, weathered, class 37 was stabled in a siding, at the time of my visit, and the 'real - or - model' photo I took, looks pretty good, the limitation being more to do with the physical bulk and size of my camera, than the standard of modelling.
The LMS 'twins' were running, and with sound too !! where did he get that from ?? remarkable...
Pete's lucky, in that he can attract some of the best O gauge modellers and modelling skills, his layout really shows what you can do, with the right people on board.
I was surprised by the sheer number of correctly assembled, Slaters wagons successfully running on the layout, - I tried building some of these kits a few years ago, and put them on lima chassis, as I didn't feel confident enough to build the kit chassis in case it wasn't 'square' or the axleboxes ended up out of line, as quite often, I'm a bit ham-fisted.
Inspirational layouts 2 + 3, seeing the 100 wagon coal train go over the viaduct at Pendon, and the dramatic scenery on Chee Tor, including the passage of the train over the bridge, through the short tunnel and then out, into some more, magnificent countryside.
