Light rail service in Denver is getting back to normal Wednesday morning after power issues disrupted service on four lines.

Light rail service on Denver’s  Regional Transportation District’s  E, F, R, and H lines between University Station, Belleview Station and Dayton Station was disrupted and bus shuttles were used to transport passengers.

RTD expected operations to resume to normal schedules by 10:30 a.m.

Bus shuttles are in place between University and Belleview Stations. All southbound H Line riders need to take the R Line to Belleview Station and transfer to the bus shuttles, RTD said in a news release.

Train riders should plan for additional travel time between affected stations.

In its news release, RTD did not provide a reason for the disruption.
