Slides from a presentation by Steve Ditmeyer, National Defense University that talks about the future of railroad system. Throughout the slides, it is evident that the model he discussed resembles very closely to the system discussed in the application, with the exception that most sensors in the model are on the track rather than the train.

Railroad traffic control system that links each locomotive to a control center for communicating data and control signals. Trains have onboard computers, sensors and two-way communication devices, information from sensors are transmitting to the control center and schedule are transmitted to trains. Although the sensor are lacking in variety compared to the application, the whole architecture and concept of a network-centric railroad system are almost identical.
