Chuck you got me interested in the history of the Lionel Alco and it's fascinating. Like most Lionel products, there were many variations, including both front and rear drive.
And yes my Alaska 1200 is front Pullmor drive with both traction tires and Magne traction. New traction tires might help and I have ordered replacements.
I'll be on the lookout for a clean late model Alco with the front Pullmor and Magne traction, to serve as donor to power my dummy, which doesn't have pickups or lighting.
Would not mine having a 2033 AA set with the die-cast frame, but I would not modify it.
