0015, 0025, 0045, 0045K and 0075
Lionel 00 tank cars were offered in both scale (0015 and 0045) and semi-scale versions (0025 and 0075). The 0015 and 0025 had three rail trucks while the 0045 and 0075 featured two rail trucks. The 0045K was a kit version of the two rail tank car.
Two rail cars would run on either two or three rail track, but three rail cars would cause shorts on two rail track.
The cars were offered in black with Shell decals and silver with Sunoco decals. The semi-scale versions did not have the tank underneath the frame. The black cars have catalog numbers rubber stamped on the bottom of the frame. The silver cars either have the catalog number on the decal or the number 2699 on the decal with the number on the frame. There are more variations of the tank car than any other Lionel 00 car.
