Bachmann 2-6-0 N Class pony truck derails

[FrankS]

Hi,

I wonder If anyone else has the same problem I have with the Bachmann CIE N Class 2-6-0 loco ???

The front pony truck derails as soon as the loco moves off the straight.

Any ideas ???

Thanx

Frank I have a few of them it's probably the spring ain't putting enough pressure on the truck. Remove the truck and bend the steel spring a little to increase the pressure. Just make sure that the truck can turn freely when you put the screw back in.
