Abstract
An exemplary method includes electronically determining that movement of a rolling stock should be prevented based on a failure condition of the rolling stock. And if it is electronically determined that movement of the rolling stock should be prevented based on the failure condition of the rolling stock, the method further includes preventing movement of the rolling stock including preventing the rolling stock from initiating a movement from a stationary position along a track within a work area defined around the rolling stock by: preventing brakes of the rolling stock from being released via one or more pneumatic components; and/or preventing the rolling stock from receiving or accepting a movement command.
Claims28
A method comprising:
- electronically determining that movement of a rolling stock should be prevented based on a failure condition of the rolling stock;
- and
- if it is electronically determined that movement of the rolling stock should be prevented based on the failure condition of the rolling stock, preventing movement of the rolling stock including preventing the rolling stock from initiating a movement from a stationary position along a track within a work area defined around the rolling stock by:
- preventing brakes of the rolling stock from being released via one or more pneumatic components;
- and/or
- preventing the rolling stock from receiving or accepting a movement command;
- wherein the method includes:
- electronically receiving a report of the failure condition of the rolling stock;
- and
- in response to receipt of the report of the failure condition of the rolling stock, electronically locking out one or more track switches, via a yard control server, that otherwise would permit traffic in and out of the track being occupied by the rolling stock having the failure condition.
A system comprising a control unit onboard a rolling stock, the system configured to be operable for electronically determining that movement of the rolling stock should be prevented based on a failure condition of the rolling stock, and if it is electronically determined that movement of the rolling stock should be prevented based on the failure condition of the rolling stock, the system is configured to be operable for preventing movement of the rolling stock, via the control unit onboard the rolling stock, including preventing the rolling stock from initiating a movement from a stationary position along a track within a work area defined around the rolling stock by:
- preventing brakes of the rolling stock from being released via one or more pneumatic components;
- and/or
- preventing the rolling stock from receiving or accepting a movement command, wherein the system is configured to be operable for:
- electronically receiving a report of the failure condition of the rolling stock;
- and
- in response to receipt of the report of the failure condition of the rolling stock, electronically locking out one or more track switches that otherwise would permit traffic in and out of the track being occupied by the rolling stock having the failure condition.
