ST. LOUIS – There are some changes on MetroLink this week that could impact your commute.

Some of the trains will have just one car instead of two. It’s mostly on the Blue Line.

The trains will still run on the regular schedules. Metro says some of the oldest train cars need repairs.

The camera systems need work because of voltage issues. Those train cars will be taken out of service for repairs. No word on how long that will take.
