Train Derailment Near Casselton, North Dakota -- November 13, 2014

A reader just wrote to tell me there's been a train derailment near Casselton, ND.

Not a Bakken crude oil train.

Monitoring area for propane leak.

Will watch for news story and link.

The reader who sent me this is reliable.

Here's the link:  http://www.valleynewslive.com/story/27381049/train-derails-near-casselton-nd:

The Cass County Sheriff's Office says they believe the two trains involved are BNSF and both were traveling at very low speeds. The train going eastbound was hauling lumber and the train going west had empty oil tankers. Approximately 25 cars were derailed between the two trains.

No injuries or fire have been reported as of 6:30 p.m. Propane tanks on BNSF property were hit during the derailment, but do not appear to be compromised.

The reader's only question: what is it about Casselton, North Dakota?

Trivia: the propane tank on BNSF property part of the rail switch mechanism, I assume; more here. The reader tells me that the tank was knocked ajar but no leak.
