Hi GS, the curves are set track with the points being streamline. Interestingly there are fewer issues when I run the loco on the inner track (2nd radius). It’s the outer track that causes the majority of derailments.
Thanks for all the suggestions. My track is Peco code 100 with Peco points. The track isn’t perfect but all my other locos manage to stay on the track. I have a mixture of Hornby and Bachman locos. I’ll keep fiddling with the pony truck but I would have expected better from the latest model.
I’ve just purchase the new Lord President. This is a superb looking loco but the front pony truck jumps the tracks on points. This doesn’t happen at low or very high speeds but does frequently happen at a realistic running speed. I had a similar problem with the Cock of the North but this doesn’t seem to be as bad. Does anyone have a suggested remedy.
