Riders on Metro should expect delays Thursday morning on the Red line, as trains are sharing a track between the Forest Glen and Silver Spring stops.

There was a disabled train near the Forest Glen stop. Passengers had to get off the troubled train.

On Metro’s bus system, it warned riders should also expect delays because of icy conditions throughout the area.

The transit agency said its bus system was running on a “moderate” snow service plan, meaning there would be delays and detours and no service on some routes.

It advised riders to go to wmata.com/snow/moderate for details.

Buses stopped running overnight because of the icy roads.
