Quick-load retail merchandising product pusher systems and methods dispense retail products, wherein the systems and methods have a fixed portion having a front end, a rear end located opposite with respect to the front end of the fixed portion, a top side and a bottom side located opposite with respect to the top side of the fixed portion. Further, the systems and methods have a movable track movably connected to the top side of the fixed portion, wherein the movable track has a front end, a rear end located opposite with respect to the front end of the movable track, a top side and a bottom side located opposite with respect to the top side of the movable track. Still further, the systems and methods have a pusher paddle configured to move one or more retail product forward away from the rear side of the movable track and front retainer teeth connecting the fixed portion and the movable track, wherein the front retainer teeth are provided on the top side and at the front end of the fixed portion and extend outwardly with respect to the top side of the fixed portion. The movable track is movable to a closed position or to an extended position, wherein, when the movable track is moved to the extended position, forward movement of the pusher paddle is restricted by the front retainer teeth.

The railway vehicle (10) includes a plurality of cars (12, 20) articulated to one another, the plurality of cars including: a single first key car (12), having a first architecture, a plurality of second cars (20), having similar second architectures different from the first architecture. The first key car (12) has no dining area.

A railway vehicle stopper includes a first rigid member, a second rigid member, a rubber elastic body, a third rigid member, an abutting member, and a communication passage. The second rigid member is arranged opposed to the truck frame or the vehicle body with an interval. The rubber elastic body elastically couples the supporting portion of the first rigid member to the second rigid member. The third rigid member is mounted inside the supporting portion of the first rigid member to form an air chamber with the second rigid member. The abutting member is coupled to at least one of mutually opposed surfaces of the second rigid member and the third rigid member. The communication passage is provided on one or both of the first rigid member and the third rigid member to communicate the air chamber with an outside.

Provided is a bearing monitoring device of a railcar, the railcar being constituted by coupling a plurality of cars including carbodies and bogies, the bearing monitoring device including: bearing temperature sensors provided at the respective bogies and configured to directly or indirectly detect temperatures of bearings of the bogies; at least one state sensor provided at at least one of the carbodies of the plurality of cars and configured to be used for calculating loads or rotating speeds of the bearings; and a storage unit provided at at least one of the carbodies of the plurality of cars and configured to store data pieces of signals detected by the bearing temperature sensors and the state sensor.

A bolster system and method of balancing a locomotive on a bolster system is provided. The bolster system is configured such that weld seams interconnect the locomotive to the bolster, and the weld seams are oriented such that when the truck or locomotive impacts another device on the rail track, the weld seams experience a shearing force along the lengths of the weld seams. In addition, prior to welding, scales such as hydraulic jacks with gauges may be used to center and balance a locomotive on a bolster. In one embodiment, four hydraulic jacks elevate the truck, bolster, and locomotive, and the locomotive is repositioned on the bolster until the hydraulic jacks have substantially similar measures.
