Hello. My Henry model is having an issue where his front bogie will pop off the track. This was pretty much the first time I've run him as I now have large enough curves for my larger engines like Henry and Gordan. I've tried adjusting the tightness of the screws securing the bogie to the chassis. I've tried adding a bit of weight to the bogie with some modelling clay (I don't want to glue anything to it before I know it might help). Gordan has the same chassis design as Henry and runs fine on my track. The really baffling thing is that I put Gordan's front bogie on Henry and Henry's on Gordan and both models ran fine. I would just leave them that way if there was a way to switch the wheels. Anyway, the only ways I can get Henry to run consistently (without parts from Gordan) is to run him with his front bogie removed or run him backwards. I'm stumped at this point, so I though I'd see if anyone had any suggestions or had dealt with this problem themselves.
