Dozens of tourists on a White Pass and Yukon Route train saw more than scenery on Sunday afternoon, when a small snowslide damaged the train.

The train was returning to Skagway, Alaska, from Fraser, B.C., when a small but fast-moving snowslide smashed out a window in one of the train cars.

None of the approximately three dozen tourists in the affected car was injured, White Pass president Gary Danielson told CBC News.

"A snow slough or a chunk of snow came down … broke off from the side of the mountain and broke out a car window on one of our parlour cars," Danielson said Tuesday.

"Occasionally you will have debris coming down, and we're just fortunate that nothing more serious happened."

Danielson said avalanche experts checked the train tracks and all of the known avalanche chutes along the route just over a week ago, before the regular service to Fraser was resumed for the season.

Sunday's incident will have no impact on White Pass tourist train service this summer, Danielson said.
