The Pengra Pass rail route, also known as the Natron Cutoff, the Cascade Subdivision, or the Cascade Line, is a Union Pacific Railroad line (originally a Southern Pacific Railroad line) connecting Eugene, Oregon, with Klamath Falls, Oregon. Construction of the line began in 1905 and was completed in the mid-1920s. [1] [2] Its name denotes a mountain pass on the Lane County–Klamath County boundary in the Cascade Mountains of Oregon, about 1.5 miles (2.4 km) from Willamette Pass. [3] The line heads southeast from Eugene, up the Cascades and over Pengra Pass, then southward beside U.S. Route 97 to Klamath Falls, where it splits in two, each track continuing into California. [4] The route has at least 22 tunnels, several snow sheds and multiple bridges across canyons.[ citation needed ] BNSF has trackage rights between Klamath Falls and Chemult. [5]
The Pengra Pass route was built to provide trains running between Eugene and California with a cheaper and otherwise more practical option than to follow the older Siskiyou Pass route, which runs south from Eugene and over Siskiyou Pass to California. The new route opened in February 1926. [6] As a result, the Siskiyou Pass route was rendered nearly obsolete. In 2008, a landslide in the area shut down rail traffic for 105 days, which forced Union Pacific trains to make lengthy detours and Amtrak to halt services between Eugene and Sacramento, severing a key west coast rail link. [7] [8] [9] In 2011, no trains had used the Siskiyou Pass route in almost a decade. [10] By 2015 however, that line was reopening to relieve I-5 of local truck traffic. On May 29, 2018, one of the tunnels, known as Tunnel 11, caved in during scheduled maintenance work, shutting down rail traffic for 3 weeks. Union Pacific rerouted their freight trains running between Northern California and Portland through a lengthy detour, while Amtrak service did not operate between Eugene and Sacramento (initially between Eugene and Klamath Falls, with a bus bridge between the two points). [11] [12] [13] [14]
Nonetheless, a major helper operation is demanded by the Pengra Pass route's 44 miles (71 km) of constant grade—the longest anywhere on the former Southern Pacific system, including Donner Pass.[ citation needed ]
The right-of-way is surrounded by waterfalls and streams running through a Douglas fir forest. At many locations, the track runs atop the steep southern slopes of the Salt Creek canyon.
Siskiyou County is a county located in the northwestern part of the U.S. state of California. As of the 2020 census, the population was 44,076. Its county seat is Yreka and its highest point is Mount Shasta. It falls within the Cascadia bioregion.
The Great Northern Railway was an American Class I railroad. Running from Saint Paul, Minnesota, to Seattle, Washington, it was the creation of 19th-century railroad entrepreneur James J. Hill and was developed from the Saint Paul & Pacific Railroad. The Great Northern's route was the northernmost transcontinental railroad route in the U.S.
The Oregon Electric Railway (OE) was an interurban railroad line in the U.S. state of Oregon that linked Portland to Eugene.
The Coast Starlight is a long-distance passenger train operated by Amtrak on the West Coast of the United States between Seattle and Los Angeles via Portland and the San Francisco Bay Area. The train, which has operated continuously since Amtrak's formation in 1971, was the first to offer direct service between Seattle and Los Angeles. Its name is a combination of two prior Southern Pacific (SP) trains, the Coast Daylight and the Starlight.
Cajon Pass is a mountain pass between the San Bernardino Mountains to the east and the San Gabriel Mountains to the west in Southern California. Created by the movements of the San Andreas Fault, it has an elevation of 3,777 ft (1,151 m). Located in the Mojave Desert, the pass is an important link from the Greater San Bernardino Area to the Victor Valley, and northeast to Las Vegas. The Cajon Pass area is on the Pacific Crest Trail.
The Denver, South Park, and Pacific Railroad was a historic 3 ft narrow gauge railroad that operated in Colorado in the western United States in the late 19th century. The railroad opened up the first rail routes to a large section of the central Colorado mining district in the decades of the mineral boom. The railroad took its name from the fact that its main line from Denver ascended the Platte Canyon and traversed South Park, hence its popular name "The South Park Line." Despite its lofty goals, the line never connected itself with the Pacific or any transcontinental line, apart from its terminal at Denver Union Station.
The Siskiyou Trail stretched from California's Central Valley to the Columbia River in Washington State; modern-day Interstate 5 follows this pioneer path. Originally based on existing Native American foot trails winding their way through river valleys, the Siskiyou Trail provided the shortest practical travel path between early settlements in California and Oregon.
The Central Oregon & Pacific Railroad is a Class II railroad operating between Northern California and Eugene, Oregon, United States. It was previously a mainline owned by the Southern Pacific Railroad (SP) between Eugene and Weed, California via Medford, Oregon. SP sold the route on December 31, 1994, in favor of using its route to Eugene via Klamath Falls, Oregon and Cascade Summit.
Oregon Route 58, also known as the Willamette Highway No. 18, is a state highway in the U.S. state of Oregon. The route, signed east–west, runs in a southeast–northwest direction, connecting U.S. Route 97 north of Chemult with Interstate 5 south of Eugene. It links the Willamette Valley and Central Oregon, crossing the Cascade Range at Willamette Pass. OR 58 is generally a modern two-lane highway with a speed limit of 55 mph (88 km/h), built through the Willamette National Forest in the 1930s.
Siskiyou Pass is a historic mountain pass in the Siskiyou Mountains of Jackson County. It is the most used pass in the U.S. state of Oregon. The Hudson's Bay Company (HBC) made the Siskiyou Trail over the pass before pioneers traversed it with their wagons, while still later it evolved into a stage road, a railroad line, and a highway route. The name Siskiyou is believed to be derived from Cree, meaning "bob-tailed horse". Siskiyou Pass is west of the summit of Interstate 5, which is known as Siskiyou Summit.
Glenwood is an unincorporated community in Lane County, Oregon, United States. It is located between the University of Oregon in Eugene and downtown Springfield on Franklin Boulevard, along the former route of the Pacific Highway, now Oregon Route 99. It is a mixed-use industrial and residential area. The unincorporated character of the area has tended to attract "experimental and individualistic" inhabitants. For decades, Glenwood, which has been seen as a blighted area, has been the subject of redevelopment projects and proposals, including a riverfront redevelopment project.
Black Butte is a cluster of overlapping dacite lava domes in a butte, a satellite cone of Mount Shasta. It is located directly adjacent to the northbound lanes of Interstate 5 at milepost 742 between the cities of Mount Shasta and Weed, California. The I-5 freeway crosses a 3,912 ft (1,192 m) pass, Black Butte Summit, at the western base of the lava domes. The lava domes were extruded at the foot of the cone of Shastina following the period of its major eruptions about 9,000–10,000 years ago.
Keechelus Lake is a lake and reservoir in the northwest United States, near Hyak in Kittitas County, Washington. Approximately fifty miles (80 km) southeast of Seattle and a few miles southeast of Snoqualmie Pass, it is the source of the Yakima River.
Rail transportation is an important element of the transportation network in the U.S. state of Oregon. Rail transportation has existed in Oregon in some form since 1855, and the state was a pioneer in development of electric railway systems. While the automobile has displaced many uses of rail in the state, rail remains a key means of moving passengers and freight, both within the state and to points beyond its borders.
Crescent Lake is an unincorporated community and census-designated place (CDP) in Klamath County, Oregon, United States. It is situated 2.5 miles (4.0 km) northeast of Crescent Lake and 2 miles (3.2 km) south of Odell Lake on Oregon Route 58, and is next to Crescent Lake State Airport. Crescent Lake was first listed as a CDP prior to the 2020 census. The north end of the CDP, at the intersection of Route 58 and Crescent Lake Highway, is known as Crescent Lake Junction.
The Shasta Daylight was a Southern Pacific Railroad passenger train between Oakland Pier in Oakland, California, and Portland, Oregon. It started on July 10, 1949, and was SP's third "Daylight" streamliner; it had a fast 15-hour-30-minute schedule in either direction for the 713-mile (1,147 km) trip through some of the most beautiful mountain scenery of any train in North America. The Shasta Daylight replaced heavyweight trains on the same route that had taken nearly a day and night to complete the run. The Shasta Daylight was the first diesel powered Daylight and the only Daylight to run beyond California. The scenic route of the Shasta Daylight passed its namesake Mount Shasta in daylight hours.
The Southern Transcon is a main line of the BNSF Railway comprising 11 subdivisions between Southern California and Chicago, Illinois. Completed in its current alignment in 1908 by the Atchison, Topeka and Santa Fe Railway, when it opened the Belen Cutoff in New Mexico and bypassed the steep grades of Raton Pass, it now serves as a mostly double-tracked intermodal corridor.
The Oregon Eastern Railway was a predecessor of the Southern Pacific Company that acquired or built most of the Natron Cutoff in northern California and southern Oregon, United States. It also made surveys and acquired right-of-way in eastern Oregon, which were subsequently sold to Union Pacific Railroad subsidiary Oregon–Washington Railroad and Navigation Company.
The Pengra Bridge is a covered bridge near Jasper in the U.S. state of Oregon. The 120-foot (37 m) Howe truss structure carries Place Road over Fall Creek in Lane County. It replaced an earlier bridge, built in 1904, that crossed the creek a few feet further upstream.
Tunnel Number 41, or the Big Hole, is a single-track railway tunnel underneath Mount Judah in the Sierra Nevada, near Norden, California.
