A system and a method may include one or more sensors disposed onboard a vehicle that may sense one or more characteristics of the vehicle. The system may include one or more processors configured to determining an identification of a switch on a route along which a vehicle moves using one or more sensors onboard the vehicle. A location of the switch is identified with the one or more sensors. A state of the switch is determined with the one or more sensors. The identification of the switch, location of the switch, and the state of the switch are communicated with an off-board database.
