Debris on the tracks and other weather-related issues were causing major delays on BART and Caltrain Sunday, officials said.

BART halted service between Balboa Park and Colma just after 9:30 a.m., because of a tree blocking the eastbound track, which damaged the third rail. Trains were single tracking through the area, according to BART spokesman Jim Allison.

It was one of several issues across the BART system, with wet weather already causing up to 10-minute delays systemwide.

Power outages around the region were also affecting BART service, causing delays in the routing of trains, Allison said.

Elsewhere, equipment problems caused additional delays at San Francisco International Airport in the Pittsburg/Bay Point and Millbrae directions.

Just before noon, Caltrain reported ongoing delays of up to an hour after trees fell on the tracks in Burlingame and Palo Alto.
