Temperatures plummeted to minus 27 on Feb. 2, 1989 as 49 runaway train cars careened down Mullen Pass above Helena. The runaway cars crashed into another train just outside Carroll College.Â
The collision derailed 15 cars and was followed by two explosions – one from a tank car and one from a nearby transformer station – knocking out electricity and heat to a large portion of the Helena area for several days.
Though nobody was killed or seriously injured, more than $10 million in damages were reported.

"Infamous 1989 train explosion was one of Helena's worst disasters"
Not even close. Not even in the top 10 maybe... MAYBE in the top 25. Do people not know the history of this town? How many times it's burned down? The fires throughout the 1870's and all the buildings destroyed? The great earthquakes of 35? No one remembers their parents or grandparents talking about the new high school that was completely destroyed? All the buildings damaged throughout this towns history due to fires and earthquakes. I haven't even got into the urban renewal fiasco and how I would argue that was the biggest disaster this town has ever faced!
No, the whole train explosion depending on where you were in town either jostled some nerves and blew out a lot of windows, but as a 'disaster' it was not even comparable to the other true disasters this town has gone through. I understand there's a desire for embellishment to garner 'clicks' on stories, but c'mon!
