SAN FRANCISCO -- A man in his 60s died at an area hospital Tuesday afternoon after the pickup truck he was driving collided with a San Francisco Municipal Railway J-Church line train near Dolores Park, police said.

The crash occurred in the area of 21st and Chattanooga streets at about 1:15 p.m. Initial reports indicate that a white newer model pickup truck was traveling eastbound on 21st Street and allegedly sped through a stop sign, striking the rear end of a J-Church line train, Sgt. Neville Gittens said.

The driver was taken to a local hospital where he was pronounced dead, according to Gittens.

The accident temporarily stopped light rail service on the J-Church line between the 16th and Church streets stop and San Jose and Ocean avenues stop, but service resumed at 4:05 p.m.

Shuttle buses will serve customers in the affected areas until service returns to normal, according to Muni spokesman Judson True.
