[1][2][3] The line was merged into the regional Northwestern Pacific Railroad in 1907; but planned physical connection was never completed.

The railroad extended 11.6 miles (18.7 km) to Keene's summit when it was reorganized with the sawmill on May 26, 1891 as the Albion Lumber Company[4] with headquarters in San Francisco.

Lumber was loaded onto ships from a wharf at the mouth for the Albion River for drying and planing in San Francisco.

This logging operation was reorganized as the Navarro Mill Company in 1886 and loaded lumber onto ships from a millside wharf.

There were numerous shorter logging branches owned by the lumber companies, but trains never reached Boonville or Healdsburg.

Later a Porter, a Hinkley, two other Baldwins, two Limas and a Ford Model T with a Martin-Parry freight and jitney body were used.
