So many broken cars.. my heart is bleeding :(This accident happened in Oshawa (Ontario) last month in a rail yard where they ship out GM vehicles.One of the guys who attaches and detaches the car haulers accidentally unhooked a set of train cars while the brakes were not set. As the yard is inclined, the set of car trains rolled down the hill and smashed a fence and then new GM cars that were in the parking lot…What a mess and what a waste… Someone’s gonna get fired!
