Although I have a Dapol/Comet-chassis Dean Goods which I'm very happy with, I was more than pleased to acquire one of these Oxford DGs as a Christmas present a year or two ago. Unfortunately the running was atrocious, with a terrible tight-spot which no amount of running-in was going to fix. I took it back to the shop ( a general model shop rather than a railway-specialised one) and after some faffing about, a controller and length of track were set up on the counter. The loco was plonked on it, given full juice backwards and forwards, and off it shot. The bloke then looked at me with a "what's your problem, mate" type of expression. I realised then that there's a gulf of understanding between what passes as acceptable running to the likes of us, and those to whom any contact with model railways may have been confined to the train set on a table, where it's enough that a loco moves at all! Happily I did eventually get a replacement DG which is a much nicer performer than a first - although still not quite as good as it should be, I feel. Anyway, I look forward to attempting to emulate your good work here, Tim.
