Glad to hear no injuries or deaths reported. Compare to the recent disaster in Quebec - at the very least we can be thankful this happened in a very sparsely populated area.
I'm writing this from across the state line in Northern Minnesota. Although normally a resident of a England, I'm back in Mn. visiting my wife's family for the holidays. We traveled to Fargo on Sunday and were returning around the time of the accident. One striking impression of how America has changed since our last visit (four years ago) is the remarkable increase in the number of freight trains. Driving north on MN-10 on Christmas Eve I was astonished by the number of BNSF oil trains heading in the opposite direction on the tracks parallel to us. I hadn't appreciated what the fracking industry (and oilsands?) are contributing to railroad freight.
