In 1907, the Southern Pacific (SP) railroad company assumed operation of the Dallas—Black Rock portion of the line.
Logs from Black Rock were dumped into the Willamette River at varying points, including Winona and Holman.
In 1965, the section between Dallas and Falls City was cut back to Buman, where a 3-mile spur led to a lime quarry.
SP continued to access the bridge and industries in West Salem via Front and Trade streets until 1980 when these tracks were also removed.
A 5-mile segment between the former SP Westside line between Gerlinger and Dallas is all that remains of the Falls City branch.
The line is owned by Union Pacific and leased and operated by the Portland & Western Railroad as the Dallas District.
