Transportation Technology Center, Inc. conducted a side impact test on a DOT-111 tank car to evaluate the performance of the tank car under dynamic impact conditions and to provide data for the verification and refinement of a computational model.
The tank car was filled with water to approximately 97 percent of its volume and sealed but not pressurized. The tank car was impacted at 14.0 mph by a 297,125-pound ram car with 12- by 12-inch ram head fitted to the ram car.
The ram car impacted the tank center and punctured both the external jacket and tank shell. The overall purpose of the program is to improve transportation safety for tank cars.
