The preset disclosure provides a control system for operating one or more locomotives in a train, the control system including a first communication unit located on-board a first locomotive of a first consist in the train; and an off-board remote controller interface located remotely from the train, the off-board remote controller interface being configured to receive or generate a locomotive control command, store the received or generated locomotive control command in a shared ledger, and relay the locomotive control command to the first communication unit. The first communication unit is configured to receive the locomotive control command from the off-board remote controller interface.

A train speed control system 100 includes a first non-contact sensor 110 that outputs measured first speed information, a first safety device 120 that receives the first speed information from the first non-contact sensor 110, a second non-contact sensor 140 that outputs measured second speed information, and a second safety device 150 that receives the second speed information from the second non-contact sensor 140 and transmits the received second speed information to the first safety device 120 at a predetermined timing. Then, when first second speed information is received from the second safety device 150, the first safety device 120 evaluates soundness of the first speed information based on a speed difference between the first second speed information and first first speed information measured by the first non-contact sensor 110 at substantially the same timing as the first second speed information, and determines control speed of a train 1 based on a result of the evaluation.

A vehicle communication system includes a wireless communication device and a controller that controls operation of the wireless communication device. The controller directs the wireless communication device to switch between operating in an off-board communication mode and operating in an onboard communication mode. The wireless communication device communicates a remote data signal with an off-board location while the wireless communication device is operating in the off-board communication mode and the wireless communication device communicates a local data signal between vehicles of the vehicle system while the wireless communication device is operating in the onboard communication mode.
