Lac-Mégantic investigators seek urgent rail safety review

The Transportation Safety Board of Canada has issued two urgent safety advisories to Transport Canada in the wake of its ongoing investigation into the deadly runaway train derailment and explosions in Lac-Mégantic.

The first advisory relates to the securing of equipment and trains left unattended.

The 72-car train involved in the Lac-Mégantic incident was unmanned when it rolled down a hill and derailed. The TSB investigation, which is still ongoing, has determined the breaking force applied wasn’t enough to hold the train on the 1.2 per cent descending slope where it had been parked for the night.

The agency has asked Transport Canada to review the Canadian Rail Operating Rules that cover securing equipment as well as the special instructions by railways to further safeguard against runaway trains.

The second advisory relates to securing trains carrying dangerous goods. The TSB is asking the regulatory body to review all operating procedures to ensure trains carrying those good are not left unattended on a main track.

More victims identified

Earlier Friday, the names of five more victims of the blast, identified through forensic testing, were released.

The bodies were among the 42 recovered from the scene in the core of the town in the aftermath of the July 6 blast. The latest victims to be named are:

- Roger Paquet, 61.

- Jo-Annie Lapointe, 20.

- Guy Bolduc, 43.

- Andrée-Anne Sévigny, 26.

- Madame Diane Bizier, 46.

Eight more people remain unaccounted for and are presumed dead.

The recovery and identification process of the victims has been hampered by a number of factors in the nearly two weeks since the deadly train derailment and explosions.

The force of the blast all but levelled the town's core, and dangerous conditions around that site have limited what work can be done and who can get to the area.

At least five investigations are continuing into the cause and culpability in the accident.

The Transportation Safety Board of Canada, which is looking into the mechanics of what went wrong with the runaway train and the safety factors surrounding the transportation of the crude oil, is holding a news conference this morning to provide an update on their investigation.
