Brassnut, I'm not very good at troubleshooting but I think there are still some things that, if you clarify them, folks on here will have very good advice for you. So,
Did this derailment just suddenly happen or has it been building up for some time?
Is it happening on just one point or does it happen on others as well?
Is derailment happening when the point is set for straight running or when it is set for turnout?
Is derailment happening on a point in a section of straight track or in a section of curved track?
Joe Keegan asked for photographs. Any chance of some close up shots?
Wrenneire asked what is derailing, so, is it locos, or coaches, or wagons?
Is it just one item or do many items derail?
Do the items derail when going forward and/or when going in reverse?
