Thanks to all for your suggestions. I have now checked the back to back measurements between the fixed wheels with a 14.5mm. track guage, and they seem to be OK. I have also looked at the points that seem to be affected the worse, and although the joints are a little bit apart, they do not seem that bad. The Q1 in question does run through a number of points OK, but I have now also noted that it derails on SOME, but not all, of the 1st radius curves. As an experiment, I ran the train without the tender, and found that it ran perfectly in reverse (with no derailments), but still the same problems in forward drive. Does this give any clues as to other possibilities? Could it be a weight problem? I have no idea how weight affects the performance of loco`s. Thanks for all the responses - I`m still hopeful of curing this frustration!

Many thanks to all for your responses. I can see now why the 0-6-0`s are more of a problem. I believe my new Jinty`s can also derail occasionally, but not as frequently as the Q1. I will carry out all the checks you mention, and hope to find a cure. Some of the track has been ballasted, so will need a lot more work if there are irregularities in the trackwork to remedy things. Still, that will teach me to carry out any track laying check runs with an 0-6-0 loco. Presumably, if the rigid wheelbase locos run OK, the rest of my stock should be alright. Or is that too simplistic??

Thanks for that Graskie. Although I restarted my interest in this hobby some 4 years ago, I have never had the courage to join a forum, in case my lack of knowledge was seen as stupidity, but I guess thats the whole point of a forum - to get advice from the more experienced hobbyist. This is my very first post, and I am sure I will need a lot more help on many other aspects of the hobby. My main interest is in creating the scenic elements of railway modelling, and although I love getting my hands on as many different loco types as possible, I have very little knowledge on the technicalities when things don`t run right. I will search this site for more info on derailments then, and in the meantime, carry out the checks you mention. Thanks again

Has anyone had any experience of the new Q1 loco continually derailing on Hornby points. I have just purchased the Southern liveried train, and get very frustrated at constant derailments over the turnouts. I do not seem to have any problems with my other locomotives (which are admittedly many years old), although I have purchased, Blackmore Vale West Country class, City of Sheffield DCC Sound, Britannia, Herring Gull A4, and United States Merchant Navy class more recently. All these run perfectly. These are all Pacifics with pony trucks. I do seem to have far more problemss with my 0-6-0 locomotives. Can anybody tell me why?
