An apparatus in one example comprises an airflow manipulating device, a portable control device, and an air pressure sensor. The airflow manipulating device is disposed between a source of compressed air and an air brake line of a train consist. The portable control device is in wireless communication with the airflow manipulating device. The portable control device is transportable by a user along the train consist during inspection of the air brake line. The portable control device is adapted to transmit a control signal over a wireless communication channel to move a valve in the airflow manipulating device to a position that causes an increase or decrease of air pressure in the air brake line. The air pressure sensor measures an air pressure level in the air brake line for wireless transmission to the portable control device. |
