Interview by Trish Kahle

On July 6, 2013, the air brakes failed on an unmanned, seventy-four-car train carrying Bakken crude oil, sending the train cascading into the Quebec town of Lac-Mégantic, where it derailed and exploded. Forty-seven people were killed, and nearly half of the downtown was destroyed in the initial blast. In total, twenty-six thousand gallons of oil spilled into the nearby Chaudière River, and soil around the town was toxic to depths of several feet.

The catastrophe in Lac-Mégantic proved to be only the first in a series of high-profile explosions. Last year, there were thirty-eight derailments across the United States and Canada that caused blasts or tank ruptures. With scenes of toxic black smoke billowing above the nation’s grasslands and residents fleeing in terror, the vehicles at the center of the lethal phenomenon were given a new name: “bomb trains.”

Yet rarely did the workers conducting and maintaining the North American rail system enter the conversation. Railroad Workers United (RWU) — a solidarity organization for railroaders across the industry’s dozen or so unions — saw an opportunity to fight for safer working conditions and build alliances with a public that fears further derailments, deaths, and ecological devastation.

One early result of that effort came last month, when the RWU brought railroad workers, environmentalists, and other labor and community activists together for two conferences — one in Richmond, California, the other in Olympia, Washington — to discuss the intersection of labor and environmental justice issues.

The conferences, as organizers readily noted, weren’t necessarily breaking new ground. They drew inspiration from earlier labor-environmental coalitions, which have a rich if overlooked history, particularly in heavy industry.

But even with the guidance the past can provide, workers and environmentalists must live in the present, where a ravaged labor movement has struggled even to win defensive battles and the environmental movement debates its strategy and future. Forging solidarity across traditional divides will be crucial in revivifying the labor movement and fighting climate change.

To that end, I recently interviewed three conference participants — RWU General Secretary Ron Kaminkow; Sierra Club community organizer Ratha Lai; and Ross Grooters, an Iowa-based locomotive engineer, environmentalist, and RWU member — about the state of the labor-environmental alliance, the working conditions on the nation’s railroads, and their vision for the future. The interviews have been edited for length and clarity.
