When a freight train filled with volatile chemicals derailed in rural Ohio earlier this month, it set off a chain of reactions: the evacuation of a town of nearly 5,000 people; a massive black plume of smoke from a controlled burn; the death of fish in local waterways; and the necessity of monitoring the local air for pollutants.

While the disaster garners headlines, researchers and chemical spill experts told Grist it’s a situation that plays out far too often across the country.

The train that derailed around 9 p.m. on February 3 was carrying chemicals used in a variety of industries, from plastics to agriculture, each with a specific degree of hazard.

The rail industry is responsible for a large share of the movement of highly volatile chemicals and explosives across the country. But for years, it has been plagued by harsh working conditions and a lack of rigorous safety standards and transparency.

Justin Mikulka, a reporter who spent years researching the rail industry’s pitfalls and disasters and wrote the book Bomb Trains: How Industry Greed and Regulatory Failure Put the Public at Risk, said weakened regulations and a rush to reopen is to be expected.

“While the trains are still burning, they’re rebuilding the rails,” Mikulka told Grist. “It’s again an excellent example of how they put profit over public safety.”

Mikulka said, be it chemicals or crude oil, trains are getting longer, going faster, and moving through the majority of the nation’s backyard. These lines are often dubbed “bomb trains” by those in the rail industry and environmental groups.

In the last two decades, train lengths have increased by 25 percent, according to the Government Accountability Office. Currently, the Federal Railroad Administration, or FRA, does not have a limit on how long a train can be. While derailments have decreased in recent years, the severity has increased as the industry focuses on longer trains with small crews.
