The CBC asked Transport Canada to clarify the rules for tying down a train a few days after the Lac Megantic tragedy. More than two days later, the response ignored the specific request for minimum requirements and referred to the Canadian Rail Operating Rules.
The guidelines in the CROR, however, lack specificity on parking trains.
Section 112, on "Securing Equipment", says: "When equipment is left at any point a sufficient number of hand brakes must be applied to prevent it from moving. Special instructions will indicate the minimum hand brake requirements for all locations where equipment is left."
The section goes on to discuss parking a train on a siding, and to specify that hand brakes need to be fully tested before they can be used to secure equipment.
Eight days after the initial request, Transport Canada continues to rebuff CBC's inquiries with vague answers.
"The rules provide specific instructions for the use of hand brakes to prevent the train from moving when equipment is not in use," it said in an email to CBC.
"Each railway has instructions that further specify how many handbrakes are applied. These instructions also govern special circumstances such as a grade. The handbrake requirements are not load specific. Requirements are determined by the amount of cars, terrain, etc."
NDP MP Olivia Chow said that's not good enough.
"Canadians need to know that the trains coming through their neighbourhoods are safe," Chow said on Thursday.
That's why the Conservatives should not hide the operations of these trains, said Chow, vice chair of the House of Commons transport committee.
"If there's nothing to hide, come clean. Tell Canadians what the operations are and whether they are safe or not."
In the early morning of July 6 a Montreal, Maine and Atlantic train, which included five engines, a boxcar and 72 cars of crude oil, left its parking spot in Nantes, Que., near the Maine border, and rumbled downhill into Lac-Mégantic. The crude oil cars separated from the engines and boxcar, and two explosions and a fire engulfed the town of 6,000.
Rescue officials have recovered 42 bodies and at least eight people are still believed missing.-

The causes of the explosions are still a mystery, but what has consumed rail experts is what precautions did MMA locomotive engineer Tom Harding take to secure the train. Did he comply with MMA's own internal special instructions for that stretch of rail? Did the MMA guidelines meet the requirements of Transport Canada?
The company originally said after the accident that Harding had put on the air brakes and left the engine running when he jumped in a taxi to go to a hotel for the night. It also said that Harding applied the appropriate number of hand brakes. A fire started in the main engine, and the firefighters who extinguished the fire were accused of shutting down the engine, which released the brakes.
Last Wednesday, MMA chairman Ed Burkhardt confused the debate by saying Harding "told us he applied 11 hand brakes and our general feeling is that now, that is not true."
That the CROR allows individual companies to set their own special instructions creates confusion, says Ian Naish, a consultant with 27 years in transportation safety.
"The rules that are applied by Transport Canada, Rule 112, says that sufficient number of hand brakes must be applied when you are stopping a train and leaving it for a bit," explained Naish. "Well how do you define that? Various railways have defined it different ways for various types of grades, or types of trains.
"The way the regulatory system has operated for the last 20 to 25 years is, basically, the railways are responsible to regulate themselves, and the federal government is the overseer, the watcher of the way they operate."-
CN and CP tighten safety rules after Lac-Mégantic disaster

Canadian Pacific, which has traditionally had the strictest rules on securing trains because of the risks of having steeper lines through the Canadian Rockies, sent out new general operating instructions to its employees last week in anticipation of stricter Transport Canada rules.
On Thursday morning, new Transport Minister Lisa Raitt said if there are going to be any new rules coming from Transport Canada, "I'll be the one announcing them. As for Canadian Pacific, I'm very pleased to see they're taking a look at theirs and I spoke to CN this week and they’re doing the same."
Company rules on 'braking, securement' kept secret
The Montreal, Maine and Atlantic, CN and CP have refused to share their special instructions with the CBC, calling them proprietary, and Transport Canada said they can’t release it because "this type of information is not in the public domain, as it involves a third-party."
But an investigator with the Transportation Safety Board, which has looked at a long list of runaway trains, derailments and crashes, told the CBC that the rules are "vague and unclear."
The investigator, who spoke on condition of anonymity, cited the 13 CN coal cars that slid downhill last year in Hanlon, Alta., crashing into a parked train.
The TSB concluded the rules were unclear, CN's standards were inadequate and the staff had problems calculating just how many cars need to be locked down by hand.
Chow argues that Transport Canada has ignored too many recommendations, not only from the Transportation Safety Board but also a scathing report by the Auditor General in 2011 which says alarm bells were raised in 2005 about transporting dangerous goods.
"Transport Canada said it would take a year or two to implement the auditor general's recommendations, but these are not new problems," said Chow.
"It's been eight years that they had no comprehensive list of what's being transported, what's the performance standard and what's the quality assurance program" for transporting dangerous goods.
"That’s not acceptable."
The answer, says Chow, is not a public inquiry, but transparency and strong government.
"Without transparency we don't know who is accountable," she told CBC Thursday. "Why do we need a government if they don't regulate?"
