A DOT-111 tank car, specification 111A100W1, constructed by fusion welding carbon steel.This car has a capacity of 30,110 US gallons (113,979 L; 25,071.8 imp gal), a test pressure of 100 psi (690 kPa), a tare weight of 65,000 pounds (29,500 kg) and a load limit of 198,000 pounds (89,800 kg).
The pressure within the tank is 25 psi (170 kPa) or lower [3] [4] 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 [5] 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 new invention patented on July 18, 1865, was for the transportation of crude oil and petroleum. It was the first appearance of an oil tank on a railroad flatcar. Three books mention his invention. [2] [3] [4] 1869: Wrought iron tanks, with an approximate capacity of 3,500 US gal (13 m 3; 2,900 imp gal) per car, replace wooden tanks.
The quantity of steam supplied could be varied by the driver to suit the demand required by a solo railcar, or plus one, or plus two, trailer vehicles. The fuel was the same diesel as was used by the railcar's engines, drawn from a separate 45-gallon tank. The water supply for the heating system was a single 100-gallon tank. [1]
Diagram showing construction of the DOT 117 tank car. The DOT-117 (TC-117 in Canada) is a type of unpressurized tank car in use on North American railroads. The DOT-117 design was developed in the aftermath of the Lac-Mégantic rail disaster of 2013 in an effort to upgrade the specifications of the then-common DOT-111 and CPC-1232 designs. [1]
The Colorado Railcar DMU is a diesel multiple unit train that was manufactured by Colorado Railcar from 2002 to 2008. The DMU was offered in single-level and bi-level versions. The DMU was discontinued after Colorado Railcar shut down in 2008.
Double-stack rail transport is a form of intermodal freight transport in which railroad cars carry two layers of intermodal containers. Invented in the United States in 1984, it is now being used for nearly seventy percent of United States intermodal shipments. Using double stack technology, a freight train of a given length can carry roughly ...
A strategy was adopted in 2004 to guide enhancements of loading gauges [27] and in 2007 the freight route utilisation strategy was published. That identified a number of key routes where the loading gauge should be cleared to W10 standard and, where structures are being renewed, that W12 is the preferred standard.
