Transport Action grieves for the loss of life in Lac Mégantic, a town on the former CPR mainline through Maine. The centre of town was wiped out with around 40 people killed by a runaway tank car train that derailed and exploded there after inexplicably leaving Nantes, Qc where it had been tied down at the end of a shift. While unattended, one of the locomotives had an engine fire, but this extinguished by local firefighter, according to RDI (CBC continuous news in French).
There are reportedly three crude oil trains per day over the Montréal, Maine and Atlantic Railway*, with crude oil coming from the Bakken Formation in South Saskatchewan bound for the (Irving?) refinery in Saint John New Brunswick. The amount of crude oil moved by tank car in Canada has grown twenty-fold since 2009, the newspapers report.
An excellent analysis of the movement of crude oil by train is to be found in TRAINS Magazine August 2013 - "Oil traffic reigns on the railways". The article contests the oft-made claim that pipelines spill less oil than rail: per million ton-miles pipelines spill 2.56 gal. (U"S") and rail but 0.13 gal. The article is by David Thomas, a business writer from Alberta.
Rail news services have so fare reported nothing in daily e-mail bulletins, although most of today's are not yet in the in-box, so we'll have to wait and see, but the usual sources are silent. The summer weekend is a factor, prudence is another, the international boundary too, but Canadian rail advocates have been very quiet, except for Denis Allard who made claims about "unsafe" older tank cars (La Presse)
