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.
