Rapido Trains Inc. N Scale: Procor GP20 Tank Car - North American Transport 'NCTX'
In the 1960s, Procor (formerly Products Tank Line) assembled their own engineering department and crafted a series of standard design tank cars which paved the way for a new generation of equipment, with many modern designs reflecting this new standard. The GP20 was suitable for lighter density commodities which would not congeal or freeze in cold weather, such as various oils and fuel. The same car could also be equipped with interior heater coil pipes, such that the contents could be heated for loading and unloading. This design was manufactured from 1969 to 1984.
