APRX 19,120 Gallon Cryogenic Tank Car

Prototype Description:

RRMods proudly represents, to as accurate detail as possible, the Chart Industries cryogenic tank car with the

frame built by TrinityRail and tanks by Chart Industries. The model SR-603 tank car is a DOT-113A120W tank car

optimized to carry maximum payloads of argon. It complies with all Association of American Railroads (AAR) and

US Department of Transportation (US DOT) regulations. The model SR-603 is a stub sill tank car – the sills are

integral to the outer tank, and the outer tank carries significant rail loads along the length of the car, and

supports the weight of the product and the inner tank.

The tank is double walled like a vacuum flask with multi-layer insulation, with the valves and fittings enclosed

in a cabinet at the lower side or end of the car. The inner tank is made of durable T-304 stainless steel, while

the outer tank is made of fine grain carbon steel. The pressure within the tank is 25 psi (170 kPa) or lower

with a temperature below 20.27 K (−423.17 °F or −252.87 °C) and a boil-off rate of 0.3% to 0.6% per day. The

inner tank is typically rated at 60 psig for improved strength and hold time with no payload loss.
