A private shuttle bus broke down while blocking San Francisco Municipal Railway tracks near Dolores Park this morning, a Muni spokesman said.

The bus broke down on the J-Church Muni tracks at the intersection of 21st and Chattanooga streets shortly after 9 a.m., blocking trains from moving through, Muni spokesman Paul Rose said.

The bus was towed away at about 9:30 a.m. but J-Church service was still recovering from the delays as of around 10 a.m., Rose said.
