I am trying to find information on a car I saw at a museum while
attending an AMICA convention several years ago.  I know I was not the
only one to take interest in this car and I discussed it with others.
I do not remember which convention or which museum.  Here is what
I remember:

The car used locomotive technology for power.  It was a large vehicle
and I think it was black.  It had an engine which I think was diesel
and I am almost certain that this ran a generator and that each wheel
(I am pretty sure it was 4-wheel drive) had an electric motor.  It is
possible that it had a hydraulic pump and motors but I am fairly sure
it was diesel electric.

Anyone with a better memory than mine?
