Lionel PRR J1a 2-10-4 #1931420 (etal)

[WALT ZIMMER]

Will the drive wheels on the Lionel PRR 2-10-4 remain on 0-72 curves or will they lose contact and overhang the rails?

[Flintlock76]

I just looked up the specs on Lionel's PRR 2-10-4, and according to Lionel the minimum curve radius for that model is 0-72.

So, as long as you run it on a layout with 0-72 or larger curves you should be OK as far as tracking is concerned.  

As an aside, I've found that sometimes  you can run a locomotive on a curve radius tighter than the factory specs, but not always.  It's best to follow the specs.
