1. 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.
