A train on its way from Spokane to Laurel derailed early Wednesday morning near Superior. Twenty three cars of the 66-cars on the train derailed, four of which ended up in the Clark Fork river.

Fortunately all four of those cars were empty according to a Missoulian report where they spoke with Montana Rail Link spokeswoman Lynda Frost. The only spillage came from carloads of 2-by-4 boards and of cedar bark and chips from a couple of cars on the bank.

Equipment had already arrived at the derailment to start cleaning up the wreckage. Here is the rest of the Missoulian report:

The derailment occurred at approximately 4:30 a.m. The train was eastbound from Spokane to Laurel. There were no injuries, and the cause is under investigation.

“We had to wait until daylight to get a better assessment,” Frost said at noon Wednesday.

The derailment happened at a “very remote location,” she added. “It’s going to take a certain amount of strategization to get those cars out of there.”

Officials estimated the Rail Link main line will remain closed until Friday morning.

Twenty-three cars from a coal train derailed in February of 2009 six miles east of the current site, closing MRL’s main line for roughly 48 hours.
