A backing ring assembly is for a railcar axle assembly including a shaft with a central axis and a bearing mounted on the shaft. An annular backing ring is disposeable upon the shaft between the bearing and a shaft enlarged section and has a central axis, an inner surface extending about the axis and defining a central bore for receiving the shaft and a retention surface facing away from the shaft enlarged section when the backing ring is disposed upon the shaft. A retainer includes an annular body, disposeable about the shaft enlarged section and having an inner surface sized to frictionally engage with the shaft enlarged section cylindrical surface, and at least one coupler connected with the annular body. The coupler(s) engage with the ring retention surface to releasably connect the retainer annular body with the backing ring to retain the ring at a fixed position on the shaft.

The present invention relates to a bogie structure for a mountain railway car. The bogie structure is configured as follows: a traction motor for driving an axle of mountain railway car is installed on a car body to simplify the bogie structure and to minimized interference between the traction motor and other components constituting the bogie, and a first and a second bearing are respectively inserted and installed between a first and a second axle and a first and a second wheel, so that a first and a second wheel located in one side close to a turning center are rotated less than a first and a second wheel located in the other side opposite thereof and a traveling distance of the wheels located in the turning-centered side is generated corresponding to a length of a turning-centered side railway, whereby the mountain railway car is improved in traveling stability.

Described herein is a system and method that can accurately determine the presence of defects in the wheelset of a railcar during active use of the railcar.

In accordance with one aspect of the present disclosure, a wear ring assembly is provided for a railway roller bearing. The wear ring assembly includes a wear ring having a central opening for receiving a journal of a railway wheel assembly and an insert including a plurality of spacers configured to extend in the opening of the wear ring to separate the wear ring from the journal. The spacers are spaced apart from each other about the wear ring. The insert may include one or more flanges that separate the wear ring from a bearing cone.
