Two NASA railroad locomotives at Kennedy Space Center move into Launch Complex 39 area's Rotation Processing and Surge Facility.

Two NASA railroad locomotives at Kennedy Space Center in Florida move into Launch Complex 39 area's Rotation, Processing and Surge Facility, or RPSF. The operation was to allow wheel and axle assemblies to be swapped between locomotives.

The RPSF was built to support work on the solid rocket used motors during the space shuttle era. The facility had never previously been used for another purpose, but is now free to serve other customers. With rails running into the building's high bay and a pair of heavy-lift cranes positioned overhead, the facility's capabilities were a perfect fit for the NASA Railroad's needs. Railroad managers wanted to trade the wheel and axle assemblies, or trucks, of locomotives No. 2 and No. 3. Locomotive No. 3 was painstakingly restored in recent years by the NASA Railroad team, and handles much of the rail work required at the center in the post-shuttle era. But the trucks on locomotive No. 2 are in better shape and are more environmentally friendly.
