Prewar Flyer 3/16" scale O gauge die cast consist. Locomotive is an Industrial Rail Atlantic. Hopper is the 1946 die cast hopper, which is the same as the prewar die cast car except for trucks. Stock car is a relettered S car with O trucks. Flat car is an S car with O trucks and an adapter coupler.
The Atlantic has no problem with pulling 5 die cast cars (1 pound each) on my layout.
