It’s been a year since a runaway train derailed near Field, B.C., killing the three crew members on board: Dylan Paradis, Andy Dockrell and Daniel Waldenberger-Bulmer. But questions remain about what led to the crash of Canadian Pacific Railway Train 301. The only formal police investigation into the derailment was done by CP Rail’s own police force. CBC investigative reporter Dave Seglins has dug into the crash for his Fifth Estate documentary Runaway Train. Today on Front Burner, he talks about what he found, and what it can tell us about safety and accountability on railways across the country.
