BROOKLINE, Mass. (AP) — A water main break in Brookline flooded train tracks and caused major delays on the D Branch of the Green Line of the Boston-area subway system during the evening commute.

Officials with the Massachusetts Bay Transportation Authority said rail service was returning to normal Friday night. The T provided shuttle bus service between the Kenmore and Reservoir stops.

The water main break happened at about 5:30 p.m. on a bridge over the tracks near the Brookline Hills station and created a waterfall onto the rails.

Work crews shut off the water and service began returning to normal just after 6:30 p.m.
