What the National Weather Service wrote

Workers with the Alaska Railroad Corporation discovered a 5 mile section of track flooded and covered with chunks of ice after an ice jam caused a 8-10 ft vertical water level rise between Talkeetna and Curry, on the Susitna River. Significant sections of track were damaged and moved horizontally by as much as 25 ft. At the same time, significant areas of erosion/damage to the railroad bed itself also occurred which had to be rebuilt. Rail service was disrupted for several days.

The wider storm

Ice Jams formed along the Susitna River during the spring breakup, which resulted in flooding along the river northeast of Talkeetna.
