(UPDATED by Radio Iowa) – Union Pacific crews are cleaning up the site of a train derailment in Carroll County. A U-P spokesman says about 36 cars derailed last (Monday) night, some two miles east of Glidden. No injuries are reported and an investigation into the incident is underway. Rural Glidden resident Connie Bock says she and her husband have lived about a quarter-mile from the tracks for more than 40 years, so they’re used to hearing all different kinds of train noise, but this was something else entirely.

“We were just watching the Olympics and usually we’ve got a lot of semis and water trailers going by for spring. They make a lot of noise, but this noise kept going and getting louder and then we could feel it in the house,” Bock says. “I decided to go out and look and I came running in and I said, ‘Should I call the police? The train has derailed.'” Bock says the noise of the derailment persisted, lasting for over a minute.

“Our dogs started barking and they usually don’t bother with the trains too much,” she says, “but they barked at this.” The derailed cars were not carrying any hazardous materials, but that was not immediately apparent to the Bocks, so they were concerned. The focus now for Union Pacific is to get the mainline operational as quickly as possible. It is not clear how long that may take, but U-P typically has blocked lines up and running within a few days.
