Older tube trailers made of steel (Type I) usually carry about 100 kg (220 lb) per load, while new and more efficient composite trailers (Type IV) made of carbon fiber make it possible to carry up to 1 tonne (1.1 short tons; 0.98 long tons) per load. Modular tube trailers range from 8 to 54 tubes. [2]
A pneumatic tube system in Washington, D.C., in 1943. Pneumatic tubes (or capsule pipelines, also known as pneumatic tube transport or PTT) are systems that propel cylindrical containers through networks of tubes by compressed air or by partial vacuum. They are used for transporting solid objects, as opposed to conventional pipelines which ...
An automated vacuum waste collection system, also known as pneumatic refuse collection, or automated vacuum collection (AVAC), transports waste at high speeds through underground pneumatic tubes to a collection station where the waste is compacted and sealed in containers. Full containers are transported away to be emptied.
The "well" is a depressed section that sits close to the rails between the wheel trucks of the car, allowing a container to be carried lower than on a traditional flatcar. This makes it possible to carry a stack of two containers per unit on railway lines ( double-stack rail transport ) wherever the structure gauge assures sufficient clearance .
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.
Wagons that are exclusively used for container transport are classified as special types. In the latter case, the profile of the wagon underframe is left open and the container only rests on the beams and the trunnions. Most container flats are designed to take standard 20 and 40 foot ISO containers. Two-axle wagons of this type are able to ...
