Looking for information on the Lionel 6418-4 16 wheel machinery car
I have several versions of this model. This diecast metal car has been issued in different colors including gray, black and red. The load included a transformer, generator or bridge girders. The metal casting has part number 6418-4 although the model has been issued with various model numbers and paint schemes. Later versions had sprung trucks.
Lionel numbers in my collection:
6-9233 with transformer (1980) gray and red versions
6-26971 6418-1 Lionel Steel with girder load (1988)
6-51600 NYC with generator load (1996)
Wanted: Photos and detailed information for other variations.
