Union Pacific Railroad Co. was rerouting train traffic on Wednesday around a section of central Iowa track damaged a day earlier in a two-train collision.
Spokesman James Barnes said 19 westbound and nine eastbound trains were diverted to other tracks since the 3:05 p.m. Tuesday accident damaged rails on two of the railroad's main east-west tracks.
A 138-car coal train traveling from Wyoming to Iowa apparently sideswiped a 94-car container train traveling from Illinois to California, Barnes said.
A locomotive and 42 rail cars o the coal train derailed, he said.
The cause of the accident is under investigation.
The track that was carrying the coal train was expected to be back in service by 3 p.m. Wednesday and the other track was expected to be repaired by noon Wednesday, Barnes said.
"We are fully engaged in the restoration operation," he said.
The collision twisted a section of the track and will require replacement of rails, ties and ballast.
Derailed cars are expected to be placed back on the rails and moved and spilled coal will be removed, Barnes said.
No injuries were reported and no chemicals were spilled, he said.
The crash site was about a quarter-mile long in a wooded area on the Meskwaki Settlement about two miles west of Tama.
Union Pacific, the nation's largest railroad, operates in 23 states including Iowa, where it has 1,480 miles of track.
The Iowa Department of Transportation says the rail line's main products handled in Iowa include grain, food and food products, chemicals/fertilizers, and miscellaneous mixed shipments.Movement of coal is one of the company's fastest growing areas of business.
The railroad said it moves more than 250 million tons of coal a year.
The railroad is the principal operating company of Omaha-based Union Pacific Corp.
