 California Northern would pick up short cuts of cars from Napa Pipe, and assemble the train in Lombard yard, usually filling two tracks.The pipe trains would sometimes be combined with Rabanco's MSW (Material Solid Waste) trains, forming 100+ - car trains, sometimes with two sets of helpers.Motive power for the California Northern had consisted of fourteen EMD GP15-1 locomotives, two EMD SD40 locomotives, two EMD SD9 locomotives, two EMD SD9E locomotives, and one EMD SW1500 locomotive, built between the late 1940s and 1970s.
