WASHINGTON — More can be done to boost the safety of moving oil by rail by focusing on the tracks themselves, according to a white paper released Thursday by a group promoting infrastructure investments.

New rules requiring more resilient tank cars are an important step, said the Alliance for Innovation and Infrastructure, but regulators, railroads and shippers now need to more aggressively combat the leading cause of derailments, including broken rail and human error.
