Hi all - i have returned to the hobby after a long break and have built a modest DCC tail-chaser layout. I've been learning a lot from online discussions and videos and things have been going pretty well - but I have one problem I don't seem to be able to solve. I purchased an Oxford Rail Dean Goods with sound and its a terrible runner. Painfully slow, it stops for no reason and if you get it going at all it kind of 'lurches' along - it has done this from the outset. I emailed Oxford and asked about this - they were nice enough to reply but didn't offer any advice. I've cleaned every wheel, pick up etc til its gleaming - and its correctly lubricated. Is there anything anyone can suggest (I was going to send it back but I managed to snag one of the tender handbrakes on its first outing!) - any advice would be gratefully rec'd! Cheers
