Abstract
An automatic identification system having a storage device mounted on the car, which includes the car identification data. A reading device is connected to a local communication node which communicates with the locomotive in a network. The local communication node communicates the read identification data to the controller at the locomotive. The identification data includes at least the serial number, brake ratio, light weight and gross rail weight of the car. The storage device is permanently mounted on the car, preferably at a junction box or pipe bracket. A current sensor is also connected to the local communication node. The storage device and current sensor are part of a subsidiary communication node under the control of the communication node.
