80's Lionel problem

[srguy]

I was at a relative's home last evening and helped to set up a late 80's NYC Flyer 4-4-2. Got it running but the front wheels kept derailing on O27 curves. Honestly a cheaply made loco with not much weight on the front wheels. I "banked" the curves a bit which kept it from derailing but the loco was still herky jerky around the curves. I run much higher end equipment and don't know what's happening here. Is the type of performance typical of this level of train?

Well it is a set engine but it shouldn't derail. Is it on a flat surface or carpet? Try turning the truck around or use a little force and try to stretch the truck spring.

There should be a spring on that front truck to hold the wheels down and prevent them from jumping the track. Typically when the front truck of a Lionel steamer frequently jumps off the track it's because the spring is worn or broken. Try replacing the spring and see if that fixes the problem.

Did you lube the loco, including the front truck?
