  • Publication number: 20180093649
    Abstract: A brake controller having independently adjustable friction and detent torque to allow for easy adjustment of handle feel without changing or replacing components. The brake handle is coupled to a cam that rotates with the handle and has a series of divots in its outer circumference corresponding to established brake handle positions. A detent roller is biased by an adjustable spring into engagement with the outer circumference of the cam and thus into the divots when the handle is moved. A separately adjustable spring biases a lateral surface of the cam into engagement with a frictional surface.

  • Patent number: 9802629
    Abstract: A system for automatically performing a bail off of the locomotive brakes in response to certain train braking operations without the need for the train operator to manually bail off the locomotive brakes. The system includes a controller that is programmed to determine when an appropriate train braking operation has been requested and to issue commands to the locomotive braking system to cause the locomotive brake cylinder to be reduced to zero pressure or a predetermined minimum pressure. The controller is also programmed to determine when an automatic bail off should be inhibited and/or cancelled depending on ongoing train conditions.
