Extensive delays were expected to last through Friday morning for Metra trains entering and leaving Union Station, after an Amtrak computer glitch halted trains for about an hour.
Amtrak’s computer control system went offline about 6:30 a.m., forcing crews to manually line the tracks.
The computer problem was fixed as of 8 a.m., but trains were still experiencing extensive delays. Some trains on the BNSF Line were running more than an hour late.
Metra spokesman Tom Miller said at 9 a.m. the agency expected the delays to clear up in the next hour or so.
Metra urged riders to listen to platform announcements and monitor its website for updates.
