A rail line that hauls double-gondola rail cars.
A double-gondola rail car, also known as a well car, is a type of double-stacked car designed to carry shipping containers. It contains an area that is depressed to allow the containers to be stacked and carried lower than a traditional flat car when attached to a train.
History
Double-gondola cars date back to the 1940s when trucking companies utilized the design in an effort to ship goods cheaper and more efficiently. The practice became highly profitable and popular within the rail industry in the 1980s.
Considerations
One of the challenges facing double-gondola rail cars in the train industry was the fact that a specialized car needed to be designed. The high center of gravity along with low tunnels across the country limited the ability to use the cars.
Features
The cars are designed to haul very heavy loads. Each car is equipped with six axles or more for durability. In addition, the containers interlock together to provide safety during transport.
Significance
According to American Rails Inc., double-gondola rail cars are most common with those companies performing intermodal services. Popular companies utilizing this technique are the Norfolk Southern Rails and BNSF Railways.
Potential
One of the major features constantly being redesigned on double-gondola rail cars is the guide assembly. This is the piece that allows for stacking and interlocking. Over time, modifications continue to be made to make this system more efficient.
