摘要： 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.

摘要： 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.
