After Ohio train crash US Senator wants answers on hazardous shipments

WASHINGTON D.C.: US Senate Commerce Committee chair Maria Cantwell has announced that she is opening an inquiry into railroad hazardous materials safety practices.

The move comes after the derailment of a train in Ohio carrying hazardous materials, which is operated by Norfolk Southern.

To help determine how to improve safety, Cantwell wrote to the chief executives of Norfolk Southern, Burlington Northern Santa Fe, Canadian National, Canadian Pacific, CSX, Kansas City Southern, and Union Pacific.

"Every railroad must reexamine its hazardous materials safety practices to better protect its employees, the environment, and American families and reaffirm safety as a top priority," Cantwell stated.
