NK-18 - GATX Pressure-Flow Cement Car

N SCALE GATX Pressure-Flow Cement Car This is a resin kit with etched brass details (trucks, couplers, decals and weights not included). It is based on Dragon, SCL, SAL, BN and CB&Q prototypes. In 1965, General American Transportation Corporation (GATX), designed a new-style covered hopper called “Pressure-Slide” for the transporting of dry bulk material. They provided only one compartment that was pneumatically discharged using an elaborate low pressure (50-80 p.s.i.) air ductwork system. The unique shape of the tank quickly led to their nickname, “whale-belly hoppers.” The 38’ 7” long cars had a capacity of 2,800 cubic feet (100-ton) of material. The Seaboard Air Line (SAL) purchased 50 from GATX in 1966. Classed LS-21, they were assigned road Nos. 7050 through 7099. These were equipped with A-3 Ride Control trucks and Timkin roller bearings. All cars were assigned to service out of Lehigh, FL. The SAL cars became Seaboard Coast Line (SCL) cars 747050 through 747099 in 1967. Some
