As shown above there are three trolley lines that surround downtown and the greater San Diego area. I started on the E Street Station Blue Line about seven miles south of downtown. I changed to the Green Line at the 12th & Imperial Station and rode it to the Grossmont Station where I changed to the Orange Line which I rode back to the 12th & Imperial Station. Then I was able to get back on the Blue Line for the ride back to the E Street Station in Chula Vista.
