Until the Burlington Northern merger in 1971, the Northwest's Own Railway served the route Spokane-Tri Cities-Portland. This story of the Spokane, Portland and Seattle is filled with trivia only a true rail buff could love. It also has some excellent -- and rare -- photos of construction and operations. The unique relationship among the 'Hill Roads' (parents Northern Pacific and Great Northern and offspring SP&S) is explored in detail and with unusual frankness and clarity. The tracks are gone now between Spokane and Tri-Cities, but the SP&S route on the north bank of the Columbia is still the mainline for BNSF and AMTRAK between Portland-Vancouver and Tri-Cities. Recently learning that Volume II to this work is available, I can't wait to read it. This volume will cover the subsidiaries and affiliates of SP&S, including Oregon Electric, Oregon Trunk, United Railways of Oregon and others.
