This branch originally extended a few miles from Los Alamitos Junction (in Stanton), through Cypress to Los Alamitos. Customers included the Los Alamitos (horse) Race Track, and more recently several industries near the end of the branch including Ganahl Lumber. The branch was abandoned in the 1990s. The eastern portion of the abandoned branch is easily located, although some of it is fenced off. The extreme western "end of branch" industrial area near Ganahl Lumber has added new buildings and it is difficult to locate the route of the branch and its spurs in that area.
