Transformer Car No. 2461 was cataloged in 1947 with a RED transformer and in 1948 with a BLACK transformer (B Variation). The transformer was decaled at the top with "Transformer" and an "L" in a circle on one side only. This decal is sometimes missing and is not shown on the A Variation example that is above. The car is die-cast metal and uses Type 3 trucks. 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.
