A farm tractor and train collided north of Cambridge this morning, but no injuries have been reported.

The accident happened just after 10 a.m. on 280th Street, just east of 580th Avenue and about 2 1/2 miles south of U.S. Highway 30.

The train clipped the front end of the tractor, knocking off the tractor’s front wheels.

The driver of the tractor, Austin Schaben, 23, of Dunlap, was eastbound on 280th Street and crossing the tracks when he saw the southbound Union Pacific train approaching, said Story County Sheriff’s Capt. Barry Thomas.

Thomas said Schaben began to back up but couldn’t clear the tracks in time.

No damage was reported to the tracks.

Schaben was working for an area farmer, Thomas said.

The 73-car train was pulled by two locomotives and was hauling mixed freight, including nut oil, wheat and sugar, said Union Pacific spokeswoman Raquel Espinoza.

The train originated in Mason City and was traveling to Des Moines, Espinoza said.

She said it was allowed to continue onto Des Moines, where more detailed inspections would take place.

The crossing was only equipped with a warning or cross-buck sign. There were no active signals or crossing arms.

"Fortunately the driver, while shaken up, appears to be OK, but this an example of how important it is that drivers use caution at rural crossings," Espinoza said. "That sign tells drivers they should yield and only proceed if it is safe to do so."
