Abstract
Currently, JSC NIIAS is developing the train control system “Anaconda” for the Northern Latitudinal Route where the railway tracks and infrastructure are located in the permafrost conditions with low population density. Therefore, the equipment of the control system is installed at stations and onboard rolling stock, and it is based on the minimally manned operation. “Anaconda” is the train separation system where train positioning is based on remote acoustic sensing of railway tracks along which vibroacoustic fiber optic cable is laid. A cable receives signals, which are partially reflected from inhomogeneous structure of the fiber optic cable. The light-sensitive detector receives the reflected signals. As a result of cable mechanical vibration caused by the rolling stock, there is the change of reflected signals that is registered by the detector. The system monitors the rolling stocks location with an accuracy of up to 10 m at a distance of up to 40 km from transreceiver. Vibroacoustic fiber optic cable along with train positioning allows broken rail detection, obstacles and staff detection on railway tracks. The equipment of the “Anaconda” system has been successfully tested and was put into trial operation on the Moscow and Kaliningrad railways.
