Looking at a diesel online, which is described as a "Lionel 8351 Diesel Locomotive Powered A unit HI Grade."
It looks like a 70-ish, budget-made locomotive, manufactured by or for Lionel, but I really can't find very much information on it specifications.
What type of motor does it have? (It doesn't look big enough to have a PulMore in it.)
How reliable or unreliable are they?
What is an "A-Unit"?
Thanks for all info.
