A guide wheel (33) for guiding a vehicle along a track is equipped with an annular tread section (61) that comes into contact with a guide rail extending along the track and a pair of sidewall sections (62) that are formed continuing from both edges of the tread section (61) in the axial direction and extend inward in the radial direction, said guide wheel (33) being characterized in that protrusions (63a, 63b) are formed over the entire circumference of each of the sidewall sections (62).

A portable, single-fixation, magnetic derailment mitigation device may be fixed on a rail track for measuring the deflection of the rail track. The magnetically fixing device is used for measuring vertical track deflection (sleeper voids), horizontal track deflection, ambient and rail temperature, rail angle, vibration, displacement, and location. The derailment mitigation device sends digital notifications and/or alarms during the live train and/or freight operations to help prevent derailments, rail buckles, breaks, and pull apart. The measured data and/or all events obtained from the derailment mitigation device is stored in the data storage such as cloud storage and viewed from any smart devices.

According to some embodiments, a railcar comprises an interior wall and guard strips magnetically coupled to the interior wall. Each of the guard strips comprises a cushioning material for absorbing impact. The guard strips are configured to prevent an object loaded in the railcar from contacting the interior wall. The railcar further comprises protected magnetic fastening systems coupling each of the guard strips to the interior wall. Each of the protected magnetic fastening systems comprises a magnet and a rod comprising a first end and a second end. The first end is coupled to the magnet, and the second end extends through the guard strip. The protected magnetic fastening system may further comprise a cup washer coupled to the second end of the rod and secured with a fastener. The cup washer partially surrounds the fastener to restrict objects larger than the cup washer from contacting the fastener.

An abrasion inspection apparatus includes: a first imaging unit installed on a track along which a vehicle is traveling, a guide wheel installed on the vehicle, the first imaging unit imaging an inside of the track; a second imaging unit installed on the track in a vehicle traveling direction with respect to the first imaging unit and imaging the inside of the track; an image acquisition unit acquiring a first image of a boundary of the guide wheel captured by the first imaging unit on a first direction side in the vehicle traveling direction, and a second image of the boundary of the guide wheel captured by the second imaging unit at the same time on an opposite side to the first direction side; and a guide wheel detection unit detecting an abrasion situation of the guide wheel according to a position of a boundary indicated in the acquired images.

A track system may include a track, a support assembly, and a flexible member. The support assembly may include a support member removably and adjustably connected to the track. The flexible member may be connected to the support member. The support member may include a pinion. The flexible member may be adjustable to a first flexible member position in which the pinion and the track are not engaged with one another. The flexible member may be adjustable to a second flexible member position in which the pinion and the track are engaged with one another.

Provided is a guide device for a rail-guided vehicle that is guided to travel along a travel track, the guide device including: guide wheels that roll in contact with guide rails arranged on both sides of the travel track; steering arms that steer the vehicle; guide wheel support members; and shock-absorbing members. One end of each guide wheel support member is supported at the tip end of a steering arm with shock-absorbing members interposed therebetween, and the other end of each guide wheel support member rollably supports a main guide wheel and a diverging guide wheel. The shock-absorbing members are disposed between each guide wheel support member and the corresponding steering arm, and mitigate the impact load transmitted from the guide wheels to the steering arms.
