It's been a trying day for light-rail riders in downtown Minneapolis, and for Metro Transit, too. Service on the Blue and Green lines was halted twice on Tuesday.

The latest disruption came around 2 p.m. when a car got stuck on the tracks near U.S. Bank Stadium. Trains were delayed for about 25 minutes while police removed the vehice.

Earlier, service was unavailable between U.S Bank Stadium Station and Target Field. The trains were not running on that stretch from late morning until early afternoon due to a mechanical issue, Metro Transit said.

The problem was due to a switch issue at Target Field Station, said Metro Transit spokesman Howie Padilla.

Trains were halted around 10:40 a.m. Replacements buses were dispatched to fill in while train service was down. Trains began running about 2 hours later at 12:45 p.m.
