Transformer Car No. 2461 was cataloged in 1947 with a RED transformer and in 1948 with a BLACK transformer. The transformer was decaled at the top with "Transformer" and an "L" in a circle on one side only of the RED transfomer. The car is die-cast metal and uses Type 3 trucks equipped with electronic coil couplers. The four steps, and two brake wheels are often broken or missing, as are the insulators at the top of the transformer. Reproduction transformers are available, but their insulators are a semi-translucent color and are more flexible than the originals. Collectors should examine the insulators before purchasing this car. There are two variations:

Variation A: RED transformer with decal on only one side. (1947)
Variation B: BLACK transformer with decal on both sides. (1948)
