Abstract
A system and method include a train including a plurality of rail cars configured to travel along a track having rails. Each of the plurality of rail cars includes brakes. A braking control unit is in communication with the brakes of the plurality of rail cars. The braking control unit is configured to control the brakes of a subset of the plurality of rail cars in accordance with braking data.
Claims24
A system comprising:
- a train including rail cars configured to travel along a track having rails, wherein each of the rail cars comprises brakes, wherein the rail cars include loaded rails cars and unloaded rails cars, and wherein a ratio of loaded rail cars to unloaded rail cars changes;
- and
- a braking control unit in communication with the brakes of the rail cars,
- wherein the braking control unit is configured to adaptively control the brakes of a subset of the rail cars in accordance with braking data based on one or both of a change in a number of rail cars in the train, or a change in the ratio of loaded rail cars to unloaded rail cars.
1 more element
A method comprising:
- communicatively coupling a braking control unit with brakes of a rail cars of a train that is configured to travel along a track having rails, wherein the rail cars include loaded rails cars and unloaded rails cars, and wherein a ratio of loaded rail cars to unloaded rail cars changes;
- and
- adaptively controlling, by the braking control unit, the brakes of a subset of the rail cars in accordance with braking data based on one or both of a change in a number of rail cars in the train, or a change in the ratio of loaded rail cars to unloaded rail cars.
A system comprising:
- a train including rail cars configured to travel along a track having rails, wherein each of the rail cars comprises brakes, wherein the rail cars include loaded rails cars and unloaded rails cars, and wherein a ratio of loaded rail cars to unloaded rail cars changes;
- one or more air compressor cars coupled to one of the rail cars at an end of the train, wherein the one or more compressor cars comprise one or more air tanks and one or more air pumps that are configured to provide compressed air to the brakes;
- an indexer along the track, wherein the indexer is configured to engage one or more of the rail cars;
- a dumper along the track, wherein the dumper is configured to dump contents from one or more of the rail cars;
- and
- a braking control unit in communication with the brakes of the rail cars,
- wherein the braking control unit is configured to adaptively control the brakes of a subset of the rail cars in accordance with braking data based on one or both of a change in a number of rail cars in the train, or a change in the ratio of loaded rail cars to unloaded rail cars,
- wherein the braking control unit is further configured to automatically determine the number of rail cars of the train,
- wherein the subset of the rail cars comprises at least two braking rail cars separated by uncontrolled rail cars, wherein the brakes of the at least two braking rail cars are controlled by the braking control unit, and wherein the brakes of the uncontrolled rail cars are not controlled by the braking control unit, and
- wherein the braking data is based on the number of the rail cars of the train, a grade of the track, a weight of each of the rail cars, and contents of each of the rail cars.
