The Libby McNeill Libby cannery at the intersection of R Street and Alhambra Boulevard in Sacramento CA was served by spurs from a Sacramento Northern Raliway line on Alhambra Blvd and a Southern Pacific branch line on R Street.
In Lodi CA, some industries were served by spurs from the Southern Pacific main line on their west side and from the Central California Traction Company (end of branch) on their east side.
I Colfax CA, a similar situation except that the second railroad was 3’ gauge (the Nevada County Narrow Guage).
