Canadian transportation officials say there will be no more one-man crews for trains with dangerous goods after an oil train derailment in Quebec that killed nearly 50 people.

Transport Canada also said trains with dangerous goods will not be allowed to be left unattended on a main track. The emergency directives take effect Tuesday.

There have been calls for tougher regulations since the July 6 tragedy, where a runaway train carrying 72 carloads of crude derailed and several cars exploded.

The unattended Montreal, Maine & Atlantic Railway train was parked overnight on a rail line before it came loose, hurtling down an incline and slamming into downtown Lac-Megantic.

Transport Canada says the cause remains unknown. Canada's Transportation Safety Board continues to investigate.
