A parked Via Rail passenger train was struck by a slow-moving CN freight train Tuesday at the train station in Jasper, Alta.

"There were two passengers that were on the one car that was struck. Those two passengers were checked out immediately by the ambulance ... at the scene and they were cleared with no injuries," said Via spokeswoman Catherine Kaloutsky.

A member of the crew was treated for shock.

The Vancouver-bound Via train was on a planned 1½-hour station stop in Jasper on Tuesday afternoon when the freight train rolled into the back of it.

Not all of the train's 270 passengers were on board at the time. The train was also carrying 27 crew members and two engineers.

The cars were being inspected to determine the extent of the damage.

Passengers started boarding the train around 5:30 p.m. MT. The train normally leaves Jasper at 2:30 p.m.

CN and Via will both investigate the crash.
