Good evening, The City of London is my first big steam train and I'm finding that there is a very high chance of it derailing when using points to change to a differing loop, eg from a curve 3 loop to a curve 2 loop. As far as I can tell, the main culprit is the tender. It seems to want to skip over the rails. The points are set correctly and I have even tried adding some additional weight to the tender in the hope of stabilizing it, but this has made no difference. I'm negotiating the points at a relatively slow speed and the derailments occur in both directions on nearly all of my points. The track is using DCC, so the points have the small shorting clips in them, but they are all tucked well out of the way. I also did a very slow run whilst shining a torch between the tender and the locomotive to ensure that there is enough clearance between the two when negotiating the points and indeed, the clearance looks fine. If I was to put a percentage on it, I'd say it is derailing around 75% of the time for any given set of points. I was wondering if I can get any advice from the more experienced? Is this kind of issue relatively common? Is there a trick to fixing it? Thanks RobP
