Wednesday brings the first Capitol Hill hearing on the risks of shipping crude oil on railways since a string of recent accidents has prompted regulators to toughen oversight of the growing practice.
Reuters sets the table for the hearing with a story that explores what lawmakers plan to ask federal regulators and industry officials.
"The pressure and volatility of these shipments have not been getting enough attention," said Rep. Rick Larsen, a Washington state Democrat, in the Reuters story.
Bloomberg looks at the Transportation Department's new testing and shipping mandates here, and quotes an official with a rail-services company who says the requirements could worsen the shortage of tanker cars.
But a lobbyist for the refining company Tesoro tells The Wall Street Journal that refiners applaud the new requirements.
