Abstract
A computer controlled brake that can selectively operate the 13 control portion exhaust magnet valve to couple the 13 pipe to atmosphere and the 20 control portion lead/trail magnet valve to pressurize the 20 pipe pressure of a trail locomotive in response to “consist swap” mode enabled while switching ends of a locomotive consist. The computer controlled brake is also configured to operate 13 control portion exhaust magnet valve to disconnect the source of 13 pipe pressure from atmosphere and to de-energize 20 control portion lead/trail magnet valve to stop pressurizing the source of 20 pipe pressure in response to sensing a rise in brake pipe from a newly established lead locomotive disabling “consist swap” mode.
Claims12
An electronic air brake system, comprising:
- a computer controlled brake having a first magnet valve that can selectively couple a source of 13 pipe pressure to atmosphere and a second magnetic valve that can selectively pressurize a source of 20 pipe pressure;
- and
- wherein the computer controlled brake is programmed to operate the first magnet valve to couple the source of 13 pipe pressure to atmosphere and to operate the second magnet valve to pressurize the source of 20 pipe pressure in response to an operator input indicating a consist swap is to take place, and
- wherein the computer controlled brake is further programmed to operate the first magnetic valve to disconnect the source of 13 pipe pressure from atmosphere and to operate the second magnetic valve to stop pressurizing the source of 20 pipe pressure in response to detection of a rise in brake pipe pressure resulting from a new lead locomotive.
A method of performing a consist swap without a risk of rollaway, comprising the steps of:
- providing a computer controlled brake having a first magnet valve that can selectively couple a source of 13 pipe pressure to atmosphere and a second magnetic valve that can selectively pressurize a source of 20 pipe pressure;
- receiving an operator input indicating a consist swap is desired;
- using the computer controlled brake to operate the first magnet valve to couple the source of 13 pipe pressure to atmosphere and to operate the second magnet valve to pressurize the source of 20 pipe pressure;
- and
- using the computer controlled brake to operate the first magnetic valve to disconnect the source of 13 pipe pressure from atmosphere and to operate the second magnetic valve to stop pressurizing the source of 20 pipe pressure in response to detection of a rise in brake pipe pressure.
