"Sens. John Rockefeller (D-W.Va.) and Ron Wyden (D-Ore.) are pressuring administration officials to act quickly on railway transports of crude oil in the wake of multiple explosive derailments."
"It's the second call for action by lawmakers, after North Dakota's senators met with officials on Thursday.
In a letter to Transportation Secretary Anthony Foxx and Energy Secretary Ernest Moniz, the chairmen of two Senate committees call for an investigation into the volumes of crude oil that are shipped by rail and whether the contents of the crude oil requires extra precaution when transported.
The letter also calls for the agencies to evaluate and update safety requirements."
