A technical problem at Union Station on Tuesday resulted in the cancellation of service on some train lines and delays of up to an hour on others, officials said.
The malfunction, related to a control plate outside the station, was identified shortly before 5 p.m., said Jeff Lustgarten, a Metrolink spokesman. Multiple inbound and outbound trains were affected as a result.
Metrolink and Amtrak trains ran on two tracks, rather than the usual five, while engineers worked to resolve the issue, Lustgarten said.
Normal service resumed at 6:25 p.m., he said.
During the slowdown, updates regarding specific Metrolink cancellations and delays were provided on the rail system’s Twitter account.
Sky5 video showed passengers waiting on platforms at the station, as immobile trains remained stranded on the tracks.
