The North County Transit District will operate extra Sprinter trains between Oceanside and Escondido to help move people to and from some of the festivities.

The transit district is most concerned with providing more transportation to handle the thousands of people expected to attend the all-day O'Fest street fair and 9 p.m. fireworks in Oceanside. Sprinters normally operate hourly on weekends and holidays, but they will run every half-hour today from 4:33 a.m. to 8:33 p.m.

The transit district will add trains that will operate from 9:30 p.m. to 11:30 p.m. For information, go to the transit district's Web site: gonctd.com.
