By the end of the 1930s, the SP operated five daily local round trips plus a number of long-distance trains between Oakland and Sacramento. The "Oakland Lark" and an unnamed local train (an Oakland connection for the "Coast Daylight") provided local service between Oakland and San Jose on the Coast Line. The inland Niles Subdivision was served by a daily Oakland–Tracy local and a commute-timed Oakland–San Jose local (which ran via Centerville and part of the Coast Line on the northbound trip and Milpitas southbound).
