A switch problem that left the Skytrain Expo Line unable to run between Commercial-Broadway Station and Waterfront Station on Sunday night was fixed after several hours.

Buses were called in at about 7:30 p.m. to help stranded Skytrain passengers. Officials initially expected to fix the problem within two hours but later tweeted that the issue wouldn’t be fixed before the service stopped for the night.

Anne Drennan, with Transit Police, said no other lines were affected by the issue.

The problem was fixed by 2:30 a.m. Monday with expectations that the morning commute wouldn’t be affected.
