Description of Driving Event:

The SRM segments are transported horizontally by standard 200-ton capacity railcars with hydraulic couplers. It was determined that the transportation design requirements for the transportation support equipment exceeded the capabilities of the railcars. There is concern for potential changes to the cases resulting from transportation in the horizontal position. As part of the case joint redesign effort, studies are being conducted to determine the effect of horizontal transportation on case ovality and, in turn, the effect of ovality on the assembly process.
