VEHICLE CONTROL SYSTEM AND METHOD FOR IMPLEMENTING SAFETY PROCEDURE
A system includes a safety mode activation device disposed onboard a vehicle system and operatively connected to a controller of the vehicle system. The safety mode activation device is configured to receive a status signal indicating a presence of one or more of an operator or an active work marker in a location proximate to the vehicle system. The safety mode activation device is further configured to transmit a lockout signal to the controller to prevent movement of the vehicle system along a route responsive to receiving the status signal.
Vehicle traction control system and method
A method and system determine, during movement of a vehicle system along a route, a tractive load demanded by the vehicle system to propel the vehicle system along the route. The vehicle system includes a propulsion-generating vehicle having plural individually controllable traction motors. A first selected set of the traction motors for deactivation is identified during the movement of the vehicle system along the route based at least in part on the tractive load demanded by the vehicle system. The traction motors in the first selected set are deactivated while at least one of the traction motors in a first remaining set of the traction motors continues to generate tractive effort to propel the vehicle system. The traction motors that are selected for deactivation may all be on the same vehicle in the vehicle system, or may be on different vehicles of the same vehicle system.

Vehicle communication system using incompatible modulation techniques
A locomotive communication system includes a lead communication device wirelessly communicating command messages to remote communication devices onboard a rail vehicle system during a messaging cycle. The lead device receives reply messages from the remote devices during the messaging cycle in response to the command messages. The lead device receives a status signal from at least one of the remote devices during a guard interval that follows completion of the messaging cycle. The lead device communicates the command message and receives the reply messages using analog modulation or digital modulation. The lead communication device also receives the status signal using the other of the analog modulation or the digital modulation. The command messages, the reply messages, and the status signal are communicated using a designated frequency channel.
VEHICLE CONTROL SYSTEM AND METHOD
A control system receives signals representing a presence and position of a secondary movement system onboard a vehicle. The secondary movement system changes movement of the vehicle without generating thrust or propulsion to move the vehicle. The control system creates a schedule of use of the secondary movement system based on the presence and position of the secondary movement system and controls the secondary movement system based on the schedule that is created.
