A trolley for inspecting railway construction parameters having two frames, left and right, joined in a folding manner with a central body, wherein each frame is provided with a running assembly mounted on the free ends of the frames, wherein the running assemblies are foldable with respect to the frames and wherein a telescopic column emerges from the central body, the final section of which has a handle for operating the trolley and a tray for resting control equipment, such as a computer, wherein the tray is foldable with respect to the telescopic column and the latter is foldable with respect to the central body until it touches the top plane of the frames, forming a compact, portable assembly that can be operated by a single operator and is easy to operate.

A system for monitoring electrical contacts for an overhead trolley line may include a wear sensor arranged such that an electrical contact on a vehicle or work machine for contacting the overhead trolley line is continually or periodically in its line of sight. The wear sensor may be configured to capture spatial data defining the surface profile of the electrical contact. The system may also include a data processing module configured to receive the spatial data and identify a defect in the electrical contact based on the spatial data.

A facility inspection system prevents a normal part from being detected as an abnormal part caused by a deviation in an alignment due to a presence/absence of a moving object in detecting the abnormal part in a surrounding environment of a vehicle moving on a track. The system includes a photographing device, storage device, separation unit, an alignment unit, and a extraction unit. The photographing device photographs the surrounding environment of the moving vehicle. The storage device stores a reference alignment point cloud and a reference difference-extraction point cloud for each position on the track. The separation unit separates the alignment point cloud from a three-dimensional point cloud. The alignment unit aligns the reference alignment point cloud and the alignment point cloud and outputs alignment information. The extraction unit extracts a difference between the three-dimensional point cloud deformed based on the alignment information and the reference difference-extraction point cloud.

Effectively control the temperature of a control unit of a railway equipment inspecting and measuring apparatus, and install the control unit of the railway equipment inspecting and measuring on the roof of the passenger car. The first space is formed between the control unit and the heat insulating case. The second space is formed between the heat insulating case and the cover. In the first space, heat is conducted between the air in the first space and the heat exchange element by the first heat conducting member, and the first fan causes circulation of the air in the first space. In the second space, heat is conducted between the air in the second space and the heat exchange element by the second heat conducting member, and the air inside the second space is diffused by blowing the air from a suction port into the second space with the second fan.

The invention relates to a method for determining an actual position of rails of a track by means of an optical sensor device, positioned on a rail vehicle, for recording the position of the track and adjacent installations. In this, it is provided that, by means of the sensor device, a course of the track and a course of the adjacent installations, in particular a catenary installation, are recorded for a track section as preliminary actual data, and that the preliminary actual data are transformed into corrected actual data in an evaluation device in that a recorded course of at least one adjacent installation is transformed into a course with a specified geometric shape. In addition, the invention relates to a system for implementing the method.

A vehicle sensor assembly includes a panel having a first side and a second side. The vehicle sensor assembly also includes a beam spaced from the panel relative to the second side. The vehicle sensor assembly further includes a mount including a first portion fixed to the beam. In addition, the vehicle sensor assembly includes a sensor coupled to the mount. The mount includes a second portion coupled to the first portion and the sensor is fixed to the second portion to define a subassembly unit. The subassembly unit is movable relative to the first portion in response to a force applied to the first side of the panel which causes the second side of the panel to engage part of the mount to move the subassembly unit. A sensor-mount assembly includes the beam, the mount, and the sensor coupled to the mount.
