Quick Specs

Product Overview

Some journeys to space begin with a much more grounded form of transportation. The WalthersMainline HO Scale Rocket Train Booster Car recreates one of the specialized heavy-duty flatcars used to transport solid rocket booster components across the country as part of NASA's remarkable rail operation.

First introduced with the Space Shuttle program in 1981, NASA's rocket train carried solid rocket boosters from Morton Thiokol in Utah to the Kennedy Space Center in Florida. The train used massive four-truck flatcars to carry rocket components beneath protective hoods, with selected cars also equipped with refrigeration units to maintain a consistent temperature for sensitive propellant loads.

Finished for Union Pacific, this model combines a familiar western railroad with one of the most specialized freight operations ever handled by rail. It is an excellent choice for a complete NASA train, a heavy-duty freight consist, or a display focused on unusual railroad equipment.

From the Space Shuttle to Artemis

NASA's original rocket train was retired in 2011 following the end of the Space Shuttle program, but rail transportation returned to this important role in 2020 with the beginning of the Artemis lunar program. Once again, specialized trains began delivering solid rocket booster components for the Space Launch System, connecting modern railroading with the next generation of lunar exploration.

Why We Love This Model

The four-truck configuration, protective hood, and substantial die-cast body make it a dramatic piece of rolling stock, whether displayed independently or included in a complete rocket train.
