Lionel Alaska #71 Work engine 0-6-0? Any pros or cons?

Hello,

I think these steam locos were made and sold about 10 years ago, and came as part of a complete train set with 4 cars.

I am seeing the engines alone for sale, as used Excellent etc., for fairly inexpensive prices.

Anybody have any experience with these?   Were they just the typical Lionel 0-6-0 Dockside engine, painted as an Alaskan?

And, was the can motor made back then any better or worse than what is being sold now?

They came with no tender, so I wonder if they have problems crossing over Lionel 022 switches?  Hick-ups, stalls, hesitations?

Thanks for any information.
