The Operating Bronx Zoo Car No. 3376 was available from 1960 until 1966 and was issued again in the last year of post-war production: 1969. The giraffe would lower its head to clear the telltale (Part No. 3424-100) that was attached to the track. Came with two AAR trucks that had either one or both disc couplers. There are five variations:

Variation A: BLUE car with WHITE lettering and a BROWN spotted giraffe.

Variation B: BLUE car with WHITE lettering and the giraffe is a solid YELLOW color.

Variation C: GREEN car with YELLOW lettering and can have either a BROWN spotted or solid YELLOW giraffe. This version came in an ORANGE picture box numbered 3376-160 (1962-63).

Variation D: BLUE car, with YELLOW lettering. This variation is hard to find.

Variation E: GREEN car, with YELLOW lettering, late AAR trucks, and a BROWN spotted giraffe. Came in a Hagerstown checkerboard box numbered 3376-160. Originally, it contained one telltale that came in an envelope numbered 3376-18 (1969).
