One speeding passenger train slammed into another stopped at a depot in eastern India early Monday, killing at least 60 people and injuring 90 others in the second major train disaster in the region in just over seven weeks.

The crash occurred in the eastern state of West Bengal, the site of a crash between a passenger train and a cargo train that killed 145 people on May 28. In that crash, the passenger train derailed before striking the cargo train, and authorities eventually blamed the crash on sabotage committed by Maoist rebels.

Indian authorities said they were still investigating the cause of Monday’s crash. Railway Board Chairman Vivek Sahay said it was possible the crash was caused by human error, adding that “no effort was made by the driver of the Uttarbanga express to stop the train.” LAT
