According to some embodiments, a railcar comprises a railcar body comprising at least one end or side arranged in a generally vertical plane. The railcar comprises a staggered ladder coupled to the railcar body and extending in a generally vertical direction. The staggered ladder comprises a plurality of steps that are staggered such that at least one step proximate a bottom of the ladder is offset from the generally vertical plane of the railcar body by a greater distance than at least one step proximate a top of the ladder. The railcar further comprises a staggered handrail coupled to the rail car body and proximate the staggered ladder, wherein a bottom portion of the staggered handrail is offset from the vertical plane of the railcar body by a greater distance than a top portion of the staggered handrail.

According to some embodiments, a railcar comprises a pair of trucks disposed near each end of the railcar. A well component supported by the pair of trucks is disposed between the pair of trucks. A pair of end sections are disposed at each end of the railcar. At least one end section of the pair of end sections comprises a well platform disposed near an end of the well. A step is coupled to the well platform and extends into the well component to facilitate operator egress from the well component to the well platform. A handrail is proximate the step, the handrail is sized to accommodate a hand of the operator. The handrail may be positioned above the step and below the well platform.

According to some embodiments, a method of improving weld fatigue performance in a railcar weld comprises identifying a railcar weld subject to dynamic loads; determining the railcar weld is prone to fatigue; applying an impact treatment to the railcar weld using transducer coupled to one or more pins, wherein the one or more pins are configured to contact the railcar weld without interference from other portions of the railcar. According to some embodiments, an impact treatment device for a railcar comprises a transducer coupled to one or more pins for imparting an impact to a railcar weld. The transducer and the one or more pins are configured to put the one or more pins in contact with the railcar weld without interference from other portions of the railcar. The transducer comprises one of an ultrasonic transducer, a piezoelectric transducer, or a pneumatic transducer.

A railcar truck and adapter pad system for placement between a roller bearing and side frame pedestal roof of a three-piece railcar truck. Many different features of the pad and/or the adapter-pad interface are configured to improve stiffness characteristics to satisfy both curving and high speed performance of the railcar truck.

A bogie axle assembly having a housing, a spindle, a drive sprocket unit, and a planetary gear set. The drive sprocket unit may be fixedly disposed on a planet gear carrier of the planetary gear set. The spindle may be fixedly disposed on the housing. The drive sprocket unit may be rotatably supported by at least one roller bearing assembly that may be disposed between the spindle and the drive sprocket unit.

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.
