So my plan today was to pull out the point motor and replace it with a Peco motor that I have, that didn't happen, I found out the blades were not moving across as they should, released the arm, and they work fine, so Hornby point motor failure, ok no problem. fitted the new motor, switches across fine.
Decided I would run a few different loco's across it to make sure, most managed it fine, the GP18's, 35',38's had a few track issues that had to be sorted, then decided to run the big guy's SD 60's and 70's, I've always had problems running the big guy's I always thought that the curve was too tight into the turnout, so ran them on both my inner track's which are much tighter, (the inner track is a 2nd radius), still had a few derailment's, but that was down to my bad track laying, sorted them out and they ran fine on the 2nd radius curve.
Ran them on the outer rail, get to the turnout, derailment 7 times from 10. (strangely only going clockwise) It seems that when the front truck enters the frog it's hitting the plastic crossover and gets sent off the rail, I've looked in my track spares and I have a few spare ones, but they are all around the same vintage, so ordered a new one, when that arrives, I'll fit it and I think I may need to re lay that outer track too. It's causing way too many issue's with the HO, that I don't get with the OO scale.
What I'm annoyed about is the smaller loco's don't seem to have an issue with the turnout, just the big guy's, I could simply not run them I know, but no point having them if their going to sit in a box and never see the light of day, I'm not a collector.
