PRR S-2 6-8-6, also by alco.
I think the engine came with a can motor as the motor mount looks factory made.
Ditto for the previous PRR T-1.
No coupler ever mounted and wheels look brand new.
With 8 wheel trucks and tender skirting, I can see why it wasn't run much as those trucks don't move a whole lot under that tender!
Came with elephant ears. No easy way to mount them other than glue so will tap/screw them to the running board.
Test run video: another quiet running engine.
Nice when you can have the entire roster of a railroad's certain class of engine!
Lionel made a lot more of these than Pennsy ever did!
