The Federal Railroad Administration (FRA) contracted Southwest Research Institute (SwRI) to evaluate the fire performance of an alternative fuel storage tank using analytical methods and fire testing. The objective of this project was to expose an LNG rail storage tank to fire conditions and observe the performance of the pressure relief valve (PRV) system. The tank was filled with liquid natural gas (LNG). SwRl performed the full scale UN-T75 portable tank tire test on June 29, 2022.
