UPDATE at 3 p.m.: The system issues have been resolved, regular service has resumed.
The Expo and Millennium Lines have been experiencing major issues since 10 a.m. due to a disruption to the SkyTrain communication system.
Problem trains are limiting Expo Line service to a single-track outbound between Commercial-Broadway and Patterson Stations. In addition, Millennium Line trains will only travel between Columbia and VCC-Clark Stations.
Passengers are advised to allow extra travel time or use alternate routes as it is not known when regular service will resume. SkyTrain technical workers are in the process of resolving the issue.
