TORONTO (AP) — Canada said Wednesday it was phasing out the type of rail tankers involved in last summer’s massive explosion of a runaway oil train that incinerated much of a town in Quebec, killing 47 people and prompting intense public pressure to make oil trains safer.

Canada’s transport minister said the DOT-111 tankers, which are used to carry crude oil and ethanol and are prone to rupture, must be retired or retrofitted within three years. Transport Minister Lisa Raitt’s announcement comes about nine months after more than 60 of the tankers carrying oil from North Dakota came loose in the middle of the night, sped downhill for nearly seven miles (11 kilometers) and derailed into the town of Lac-Megantic. At least five of the tankers exploded, leveling about 30 buildings, including a popular bar that was filled with revelers.
