MONTREAL - A husband and wife in their 50s are dead following a collision Wednesday afternoon between a train and a pick-up truck in west-end Montreal.

The victims are Luigino (Luigi) Parissi and his wife Vittoria (Vicky). Luigi worked at a Rona in Notre-Dame-de-Grace, near the site of the accident.

Police say the truck flipped over an overpass and headed down an embankment on Highway 20 west close to Sainte-Anne-de-Bellevue Blvd. in Montreal West near the Ville-St-Pierre Interchange.

It ended up on the tracks, where it was hit by an oncoming train.

It's unclear whether the pair died in the fall or the train collision.

It appears the driver may have lost control of the truck, said Montreal police spokesperson Andre Leclerc.

Police say Vicky made a phone call moments after the accident occurred. Both were pronounced dead at the scene.

The police report on the accident may take a few weeks to complete, said police.

An autopsy is expected to be performed on the pair.

Leclerc said he is trying to determine how the vehicle managed to flip over the guardrail, though they are speculating the incident may have been caused by poor road conditions.

"Wind and snow may be one of the factors, but we'll have to confirm this with technicians," said Leclerc.

The train was VIA rail train 56 travelling from Toronto to Montreal.

No one was injured on board the train.

The overpass at Highway 20 west close to Sainte-Anne-de-Bellevue Blvd. was closed to traffic Wednesday afternoon.
