Some of the region’s transportation services are running on a limited schedule with today’s Columbus Day holiday.

Metro’s rail system opened at 5 a.m. today and is closing at midnight.

Trains will run on a Saturday service schedule, meaning they’ll run every six to 12 minutes during the day. Riders will pay off-peak fares all day.

No track work is scheduled for Monday. Parking at Metro-owned facilities is free.

Metrobus is operating on a Saturday schedule so some trips after midnight will not operate. The transit agency recommends riders check schedules.

The door-to-door-service for Metro’s disabled riders — MetroAccess — will operate on its regular schedule but subscription trips will be canceled. To make a reservation for a subscription trip, call MetroAccess, officials said.

Metro has sometimes done more track work over three-day holiday weekends because ridership is typically lighter. But it has received criticism from some commuters who do not get Columbus Day off and complain there isn’t enough service.

The transit agency had decided in June to  not do weekend track work over Columbus Day.

In the District, parking meters are not in effect due to the holiday.

MARC service also is not running, and in a change, VRE is running on an “S” schedule for today’s  holiday.
