Amtrak trains are still on track to run the last of their scheduled service on a track that could be used for a fatal crash in a Colorado mountainside.

The Colorado Springs Gazette reports that Amtrak said the train was still on its scheduled route Sunday evening, though the railroad has not yet released the exact route.

It is unclear if the train’s route will change after a crash on Sunday.

Officials with Amtrak said they were monitoring the situation, but did not have any details about the crash.

A spokeswoman for the railroad said that no specific details have been released about the incident.
