I think it's sufficient for Skew Bridge, though if I'd got room for more sidings on the scenic side of the laytout then I'd consider filling those up too for effect!
I think they're decent enough runners, very little wobbling around, and on the whole they stay on the track as they're supposed to. The buffers are wrong as many are keen to point out but who notices when they're in motion?
As I've remarked elsewhere, the majority of my MGR's were purchased 10 or more years ago, mostly secondhand, and I was averaging around £8 per wagon. Later purchases cost me up to £41 for the triple wagon packs which is as much as I'd be willing to pay. Nowadays they're asking over £20-£25 per wagon?
Well if I operate it as intended, the loco's used on Skew Bridge shouldn't ever be seen on Worsley Dale as they're supposed to be entirely different layouts. On the odd occasions some loco's have found their way across however but generally it's better for me, and less hassle, to keep them in their proper places.
