A railway track condition monitoring system including a plurality of sensors installed on a rail of the track and spaced by a predetermined distance from each other. The sensors having respective signal acquisition and recording means for the acquisition and recording of an acoustic signal being generated by an approaching train and propagated by the rail or by a ground carrying the rail. A signal transfer means for the transfer of an acquired and recorded signal to the passing train by wireless transfer at the time of passing of the train in proximity to sensors, and a signal analyzing means for analysing transferred ones of the acquired and recorded signal on-board the passing train. The signal analyzing means may be adapted to compare in a processing unit the signals from adjacent sensors and on that basis indicate a rail discontinuity.

A ground base device includes a schedule timetable storage unit storing a received schedule timetable periodically transmitted from the central control device; a departure-obstructed condition determination unit determining whether a departure-obstructed condition of a train is resolved and outputting departure-obstructed condition cancel signal when the departure-obstructed condition is resolved; a departure time control unit outputting departure-time appropriate signal when current time is departure time based on the schedule timetable upon receiving the departure-obstructed condition cancel signal; a departure interval control unit outputting departure-interval appropriate signal when intervals between the train and preceding and following trains are a threshold value or more upon receiving the departure-time appropriate signal; and a departure instruction signal output unit outputting a departure instruction signal upon receiving the departure-interval appropriate signal, and, when the central control device fails, the departure time control unit uses the schedule timetable received when the central control device is normal.

A railway vehicle control method includes: receiving information of a target railway vehicle in front of a current railway vehicle and a current speed of the current railway vehicle; controlling, based on the information of the target railway vehicle and the current speed, the current railway vehicle to operate, and determining an operation requirement for the target railway vehicle; and transmitting the operation requirement for the target railway vehicle to a central server.

A control system for a train includes a display unit providing a first display including a plurality of distance counters simultaneously, wherein the plurality of distance counters includes at least a count up counter and a countdown counter. The control system further includes a controller configured to continually increment or decrement at least one of the count up or countdown counters based at least in part on a track distance covered by the train.

System includes a control system used to control operation of a vehicle system as the vehicle system moves along a route. The vehicle system includes a plurality of system vehicles in which adjacent system vehicles are operatively coupled such that the adjacent system vehicles are permitted to move relative to one another. The control system includes one or more processors that are configured to (a) receive operational settings of the vehicle system and (b) input the operational settings into a system model of the vehicle system to determine an observed metric of the vehicle system. The one or more processors are also configured to (c) compare the observed metric to a reference metric and (d) modify the operational settings of the vehicle system based on differences between the observed and the reference metrics.

A communication apparatus is mounted on a train and forms a train communication system together with a system control apparatus that generates control frames including general and low-latency frames. The communication apparatus includes: a general transfer processing unit that stores the general frame; a low latency transfer processing unit that stores the low-latency frame, the low latency frame requiring transferring with lower latency than the general frame; a frame identification unit that identifies priority of the control frame and outputs the control frame to the general transfer processing unit or the low latency transfer processing unit based on a priority setting table indicating the priority of the control frame and set in the identification unit; an output control unit that preferentially transfers the low-latency frame over the general frame; and a control unit that modifies the priority setting table.

A predetermined image processing is carried out on the images that have been taken by the cameras 101 through 108 attached to a side of the cars that form a train before the images are displayed on the monitor 301 that is mounted in the train. That is to say, as a first image processing, among the images to be displayed, a left-right inversion process is carried out on the images where the positional relationship between the cars and the platform in the image is opposite between left and right to the positional relationship as viewed in the direction in which the train is to travel. In addition, as a second image processing, a cutout process is carried out on the images to be displayed so that the cutout regions differ in accordance with the opening and closing state of the doors.

In order to locate points or lines of interest (A, B, C, D, A′, B′, C′, D′, 162, 163, 164) of a railway track (22), by means of a railway locating system (12), progressing on the railway track (22), a linear camera (26) pointing at the railway track (22) repeatedly acquires instantaneous linear optical data along an instantaneous measurement line (50), and an orientation device (52) of the railway locating system (12) repeatedly acquires orientation data of the railway locating system (12) with respect to a reference line (22A) of the railway track (22). By processing at least the instantaneous linear optical data, a potentially distorted bitmap image is constructed of a zone of the surface of the railway track (22), then points or lines of interest (A, B, C, D, A′, B′, C′, D′, 162, 163, 164) are identified in the potentially distorted bitmap image, before determining rectified coordinates of the points or lines of interest (A, B, C, D, A′, B′, C′, D′, 162, 163, 164), as a function of potentially distorted coordinates of the points or lines of interest (A, B, C, D, A′, B′, C′, D′, 162, 163, 164) in a reference system of the potentially distorted bitmap image and orientation data.

There is provided a train monitoring system using a train monitoring device that is mounted on a train and uses a plurality of cameras for imaging around the train from different sides. The train monitoring device includes a control unit that is configured to, when the train stops at a station, select one of the plurality of cameras as a rear imaging camera for imaging a rear side in a traveling direction of the train, after the train departs from the station, acquire image data imaged by the rear imaging camera, and transmit the image data to the outside.

A system and method determine that a vehicle system is beginning rearward movement based on one or more characteristics of the vehicle system that are monitored by a movement sensor. A warning device is controlled to sound a notification to one or more locations off-board the vehicle system. The warning device is prevented from controlling the warning device to generate the notification while the vehicle system is moving in a direction other than the rearward movement. The warning device is permitted to generate the notification responsive to determining that the vehicle system is beginning the rearward movement.
