TRACY -- An Altamont Corridor Express train was recovering from delays of up to 20 minutes after hitting a cow Monday evening, authorities said.
The cow collision occurred shortly after 7 p.m. The crew of ACE train No. 8 assessed the train for damage and replaced a broken hose from spare parts already on board, ACE spokesman Steve Walker said.
The eastbound seven-car train carrying about 250 passengers apparently struck the cow after it wandered onto the tracks outside the Tracy station, Walker said.
"It's not uncommon, as our route is mostly rural and that part of Tracy right there has a lot of farmland," Walker said. "We're not sure how the cow got onto the track, but 99 percent of the time there's a hole in a fence."
Walker said ACE would try to find the rancher and urge them to inspect their fenceline to prevent a repeat incident, and said Union Pacific Railroad crews would clear track debris.
No one aboard the train was injured, Walker said.
The agency's last major delay came March 7 when its No. 10 train derailed into the rain-swollen waters of Alameda Creek in Niles Canyon about a mile west of Sunol. Nine of that train's 196 passengers suffered injuries and were treated at area hospitals.
