The present disclosure relates to a track travelling device, comprising a vehicle body, a connection device and two groups of wheels. The two groups of wheels are disposed on two sides of the vehicle body respectively and the wheels comprise rims matched with tracks. One end of the connection device is connected to a bottom of the vehicle body and the other end of the connection device is connected to the wheels. The connection device comprises an elastic member and the elastic member is configured to be deformed under the gravity of the vehicle body to adjust distances between the rims of the two groups of wheels. Under the gravity of the vehicle body, the track travelling device of the present disclosure can closely attach the rims of the wheels to side surfaces of the tracks, thereby preventing the vehicle body from swaying side to side. Meanwhile, the connection device comprises the elastic member for adaption to a change of a track gauge.

A method, device, and system for detecting a current leak in a traction power rail. Magnetic or electrical properties of the rail are measured. The measurements are performed using a rail instrument that senses the properties around the rail at various times while the instrument is being moved down the rail, such as using a cart or train. The rail instrument may be a flux concentrator or open Rogowski coil. The locations of the rail, about which the readings are taken by the rail instrument, may be determined and correlated with the measurements themselves. The method may comprise measuring the magnetic field of the rail along a length of the rail, and identifying a leak based on differences between the magnetic field measurements. The system may comprise a cart comprising the rail instrument and a location instrument.

The present invention relates broadly to a railway track trolley (10) generally comprising a collapsible chassis (12), two pairs of wheels (14a/b) and (16a/b), and a platform assembly (18). The collapsible chassis (12) includes a pair of opposing beams member (20a) and (20b) interconnected by a pair of adjustable cross-members (22) and (24). The pair of wheels (14a) and (16a) are removably mounted to opposing ends of one of the beam members (20a) whereas the other pair of wheels (14b) and (16b) are removably mounted to opposing ends of the other of the beam members (20b). The railway tracks (26a) and (26b) may be separated at one of a plurality of predetermined track gauges and the collapsible chassis in an expanded condition is designed to match the required lateral separation of the opposing rail members (26a/b). The invention is also directed broadly to a gate catch assembly (90) generally comprising a coupling sub-assembly (92), and a catch sub-assembly (96) configured to be releasably engaged by the coupling sub-assembly (92). The gate catch assembly (90) may be installed in conjunction with the platform assembly (18) of the railway track trolley (10) of the earlier aspect of the invention.

Various embodiments of an autonomous rail vehicle that can travel ahead of a locomotive at a distance proportional to the locomotive's stopping capability are disclosed. The rail vehicle may scan its surroundings, gauges track conditions, and communicates with locomotive operators of the scanned results in real-time to timely enable activation of the locomotive's emergency brakes in case of detection of off-normal track conditions. The rail vehicle may paired with the locomotive and provides eyes to locomotive operators so that they can have information on tracks viability well ahead of the locomotive.
