A Chicago Transit Authority computer program that allows riders to track buses and find arrival times at stops went down Wednesday morning, but was up and running by the afternoon.

The Bus Tracker program went down about 9 a.m. due to a technical problem, the CTA said. It was back up and running by 2:30 p.m.

A spokeswoman for the CTA said the issued was related to a “software glitch.”

No further disruptions were expected.
