This is about as railroad as San Diego gets. Just south of downtown and the Padres' Petco Park, the San Diego trolley, local shortline San Diego & Imperial Valley and BNSF each have small yards next to each other. Additionally, during the weekdays Coaster trainsets will layover in the SD&IY yard, meaning it is theoretically possible to get four of the five railroads in SD in one shot (missing only Amtrak).
