The Transportation Safety Board has figured out why two trains derailed near Portage last week.
The two trains actually collided with each other, causing the derailment.
Two locomotives from the eastbound train and eight train cars from the westbound train derailed.
The fire chief in Portage says it’s lucky the trains didn’t explode because one was carrying hazardous material.
One of the trains leaked diesel fuel 200 metres from the Assiniboine River.
The investigation is continuing.
