Lionel 2243150 O, Union Pacific Rocket Booster Idler Car Set, 6 car set

Perfect for use with the Lionel rocket booster flatcars or previous versions, this set of idler cars matches prototypes used by Union Pacific to help provide additional braking power and weight distribution. The lead car features newly tooled door openings and clearance arms designed to protect the oversized loads. The six-car set features uniquely numbered cars, each one matched to a car used in buffer service on these special trains. When not needed for special duty, these cars could be returned to your general freight pool just like the prototypes.
