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.

In order to position a set of one or more tools supported by a railway intervention vehicle progressing on a railway track (22), data is received characterising a curvilinear abscissa of a spatial indexation marker (56) of known signature, and a positioning of the spatial indexation marker (56) with respect to a reference line (122A, 122B, 222) of the railway track (22), and coordinates of points or lines of interest (A, B, C, D, A, B, C, D, 162, 163, 164) in a two-dimensional locating reference system linked to the spatial indexation marker (56) and to the reference line (122A, 122B, 222), one or more transposition matrix cameras (44) acquire a set of one or more transposition bitmap images in a spatial reference system of the transposition system (16), fixed with respect to the transposition chassis (45), and an odometer (28) acquires progression data of the transposition system with respect to the railway track (22). Then the spatial indexation marker (56) in the set of one or more transposition bitmap images is identified as a function of the progression data and curvilinear abscissa data, which makes it possible to determine data characteristic of the spatial indexation marker (56) and the reference line (122A, 122B, 222) in the spatial reference system of the transposition chassis, and to calculate transposed coordinates of the points or lines of interest (A, B, C, D, A, B, C, D, 162, 163, 164) in the spatial reference system of the transposition system (16), as a function of data characteristic of the spatial indexation marker (56) and the reference line (22A) in the spatial reference system of the transposition system, and coordinates of the points or lines of interest (A, B, C, D, A, B, C, D, 162, 163, 164) in the locating reference system.

In order to locate points or lines of interest A, B, C, D on a railway track 22, by means of a railway locating system 12 comprising a linear camera 26 and an odometer 28 progressing on the railway track 22 in a direction of progression 100, the odometer 28, repeatedly acquires instantaneous positioning data of the linear camera 26 with respect to the railway track 22 in the direction of progression 100, and the linear camera 26 pointing at the railway track 22 repeatedly acquires instantaneous linear optical data along an instantaneous measurement line 50. Then, by processing at least the instantaneous linear optical data and the instantaneous positioning data, a bitmap image is constructed of a zone of the surface of the railway track 22, and, in the bitmap image, at least one spatial indexing marker 56 of predetermined signature and its positioning relative to a reference rail 22A of the railway track 22 is identified. Points or lines of interest A, B, C, D are identified in the bitmap image, and the coordinates of the points or lines of interest are determined in a two-dimensional locating reference system O, x, y linked to the spatial indexing marker 56 and to the reference line 22A.

A railcar hatch control system and method for operating railcar hatches of a multi-railcar train is disclosed. A multi-railcar train may have a locomotive and a plurality of railcars having railcar hatches that can be opened and closed. The system and method may include displaying railcar identification information for the railcars on an operator display device, and receiving selections of railcars from an operator that will have a railcar hatch operation performed thereon, such as opening or closing the hatches. The railcar hatch operation is input, and the system and method control the railcar hatch operation being performed only on the selected railcars, and not on the railcars that have not been selected by the operator. The system and method may have operator interfaces devices at an operator station of the train, or at a remote location or on a remote device that communicates wirelessly with the train.

A device attached to a railcar of a train is provided. The device comprises a radio frequency (RF) transceiver to transmit and receive a RF signal. The device includes a RF modem configured to convert the received RF signal into a low frequency (LF) analog signal. The device includes a digital signal processor to process the LF signal. The digital signal processor includes a phase detector, a loop filter, and a digitally controlled oscillator. The phase detector compares the LF signal and a reference signal to generate an error signal. The phase detector also determines a state of the digital signal processor, the state being one of a lock state or an out of lock state. Further, the phase detector detects an event that the RF signal is lost and generate a loss signal. The loop filter filters the error signal and generates an error control signal. The digitally controlled oscillator generates the reference signal based on the error control signal, the state, and the loss signal.

The power battery pack is an enclosed installation isolated from external air. An inert gas injection pipe, a smoke detector and a temperature detector are arranged at the top end inside the power battery pack. An inert gas storage device is arranged outside the power battery pack. The inert gas storage device is connected with the inert gas injection pipe. A pressure detector and an inert gas injection control switch are arranged in turn on a pipeline through which the inert gas storage device discharges an inert gas to the power battery pack. The pressure detector and the inert gas injection control switch are connected with the rolling stock microcomputer system.

The first communication unit is configured to receive the locomotive control command from the off-board remote controller interface.

A sensor device includes an audio sensor and a wireless communication module. The audio sensor is configured to be mounted on a railroad vehicle. The audio sensor is configured to (i) monitor sounds emanating from one or more wheels of the railroad vehicle as the railroad vehicle moves along a track and (ii) generate sound data associated with the monitored sounds emanating from the one or more wheels. The wireless communication module is configured to transmit a broken wheel signal responsive to a determination that a portion of the generated sound data is indicative that a first one of the one or more wheels is damaged or broken.
