TORONTO/WASHINGTON (Reuters) - Political pressure to quickly improve the safety of crude oil rail shipments intensified in Washington on Thursday, while Canadian officials said two of the cars involved in the latest fiery derailment were of an older variety long faulted by regulators.
After two more dramatic oil-train incidents in just two weeks, several U.S. lawmakers urged swift measures from Transportation Secretary Anthony Foxx, who in turn promised that tougher federal standards for tank cars would come "in weeks, not months," according to North Dakota's Republican Senator John Hoeven.
