Signaling system and control method of moving vehicle
A signaling system includes an on-board device provided for a moving vehicle traveling on a track, and a station interface device provided for a station, and a branch provided on the track. A second moving vehicle transmits different moving vehicle related data of itself to a first on-board device of a first moving vehicle. The first station interface device transmits station related data of the branch to the first on-board device. The first on-board device outputs a command which instructs to switch the branch, to the first station interface based on the different moving vehicle related data and the station related data, to secure the traveling route. The first station interface device switches the branch and secures the traveling route. The first on-board device determines the traveling of the first moving vehicle of the secured traveling route based on the different moving vehicle related data.
HIGH THROUGHPUT TRANSPORTATION SYSTEM WITH SEAMLESS CARRIAGE SWITCHING BETWEEN TRACKS ALONG THE VERTICAL PLANE
The present invention relates to the field of automated transportation systems. Particularly, it relates to a transportation system comprising guide-ways or tracks, vehicle units [100, 100a] with wheel-axle assembly for switching of vehicles from primary [20] to secondary track [22] on changing trajectory to maintain same vertical plane and the method. It comprises of central controller [101], vehicle chassis with main wheels [2W], guide wheels [4iw, 4ow], guide blocks [05, 06], actuator [09]. The chassis [30] has set of contractible axles fixed to wheels [2W] to enables movement from primary [20] to secondary track [22] by withdrawing the wheels [2W] from expanded position [C] to contracted position [C] or vice-versa. The forces required to compress the spring loaded axle axis is derived from inner guide wheels rolling over the edge flange [26] when swung using single linear motor actuator [09] and related electronic controls.

Distributed bogie diagnostics for track monitoring
A method of monitoring a track using train cars includes collecting first sensor data corresponding to a track location by a first sensor network on a first train car. Based on the first sensor data, a potential track anomaly at the track location is identified by a diagnostics system on the first train car. A message describing the anomaly is transmitted to diagnostics systems located on other train cars. The message is received by a second diagnostics system on a second train car located behind the first train car. The second diagnostics system determines a time at which the second train car will be passing over track location and, at the determined time, collects second sensor data. If the track anomaly is present in both the first sensor data and the second sensor data at the track location, a train control system is notified of the track anomaly.
