Tanana Valley Railroad
The Tanana Valley Railroad (TVRR) was a narrow gauge railroad that operated in the Tanana Valley of Alaska from 1905 to about 1917. A portion of the railroad later became part of the Alaska Railroad. History The TVRR was incorporated as the Tanana Mines Railway in 1904, construction on the first section started and completed in 1905. The main speaker at the gala golden spike ceremony was Judge Wickersham and Mrs. Isabelle Barnett accepted the golden spike. The builder was Falcon Joslin who was called the "Harriman of the North". It was renamed the Tanana Valley Railroad in 1907. The company declared bankruptcy and was liquidated c. 1917. The U.S. government purchased the railroad in June 1917, and the section between Fairbanks and Happy was converted to dual gauge by the Alaskan Engineering Commission, in order to complete a railroad line from Seward to Fairbanks. This line became the Alaska Railroad (Alaska RR) in 1923. The Alaska RR continued to operate the former TV ...

Chatanika, Alaska
Chatanika is a small unincorporated community located in the Fairbanks North Star Borough, Alaska, United States, north-northeast of the city of Fairbanks. The community runs along an approximately stretch of the Steese Highway, the majority of which sees the highway paralleled by the Chatanika River. The community consists of sparsely scattered residential subdivisions, several roadside businesses, a boat launch where the Steese Highway crosses the Chatanika River, relics of past gold mining operations in the area and the Poker Flat Research Range operated by the Geophysical Institute of the University of Alaska Fairbanks. Chatanika was one of over a dozen small communities in the vicinity of Fairbanks whose prosperity was tied to gold mining during the Fairbanks Gold Rush. Chatanika, as the northern terminus of the narrow-gauge Tanana Valley Railroad, also owed much of its early prosperity to railroad operations, which were closely tied to the mining activity. Chata ...

Steam Locomotive
A steam locomotive is a locomotive that provides the force to move itself and other vehicles by means of the expansion of steam. It is fuelled by burning combustible material (usually coal, oil or, rarely, wood) to heat water in the locomotive's boiler to the point where it becomes gaseous and its volume increases 1,700 times. Functionally, it is a steam engine on wheels. In most locomotives, the steam is admitted alternately to each end of its cylinders, in which pistons are mechanically connected to the locomotive's main wheels. Fuel and water supplies are usually carried with the locomotive, either on the locomotive itself or in a tender coupled to it. Variations in this general design include electrically-powered boilers, turbines in place of pistons, and using steam generated externally. Steam locomotives were first developed in the United Kingdom during the early 19th century and used for railway transport until the middle of the 20th century. Richard Trevithick ...

Transportation In Fairbanks North Star Borough, Alaska
Transport (in British English), or transportation (in American English), is the intentional movement of humans, animals, and goods from one location to another. Modes of transport include air, land (rail and road), water, cable, pipeline, and space. The field can be divided into infrastructure, vehicles, and operations. Transport enables human trade, which is essential for the development of civilizations. Transport infrastructure consists of both fixed installations, including roads, railways, airways, waterways, canals, and pipelines, and terminals such as airports, railway stations, bus stations, warehouses, trucking terminals, refueling depots (including fueling docks and fuel stations), and seaports. Terminals may be used both for interchange of passengers and cargo and for maintenance. Means of transport are any of the different kinds of transport facilities used to carry people or cargo.

Trestle Bridge
A trestle bridge is a bridge composed of a number of short spans supported by closely spaced frames. A trestle (sometimes tressel) is a rigid frame used as a support, historically a tripod used to support a stool or a pair of isosceles triangles joined at their apices by a plank or beam such as the support structure for a trestle table. Each supporting frame is a bent. A trestle differs from a viaduct in that viaducts have towers that support much longer spans and typically have a higher elevation. Timber and iron trestles (i.e. bridges) were extensively used in the 19th century, the former making up from 1 to 3 percent of the total length of the average railroad. In the 21st century, steel and sometimes concrete trestles are commonly used to bridge particularly deep valleys, while timber trestles remain common in certain areas. Many timber trestles were built in the 19th and early 20th centuries with the expectation that they would be temporary. Timber trestles were use ...

Yukon
Yukon (; ; formerly called Yukon Territory and also referred to as the Yukon) is the smallest and westernmost of Canada's three territories. It also is the second-least populated province or territory in Canada, with a population of 43,964 as of March 2022. Whitehorse, the territorial capital, is the largest settlement in any of the three territories. Yukon was split from the North-West Territories in 1898 as the Yukon Territory. The federal government's ''Yukon Act'', which received royal assent on March 27, 2002, established Yukon as the territory's official name, though ''Yukon Territory'' is also still popular in usage and Canada Post continues to use the territory's internationally approved postal abbreviation of ''YT''. In 2021, territorial government policy was changed so that “''The'' Yukon” would be recommended for use in official territorial government materials. Though officially bilingual (English and French), the Yukon government also recognizes First Natio ...

Alaskan Engineering Commission
The Alaskan Engineering Commission (AEC) was a U.S. Federal agency, sometimes known by its initials or by alternate spelling Alaska Engineering Commission. It was created by the Alaska Railroad Act in 1914 by U.S. President Woodrow Wilson in order to arrange for the construction of a railway system in Alaska. William C. Edes was named chairman, chief engineer Colonel Frederick Mears. In 1915, the AEC became part of the U.S. Department of the Interior. In 1923, after the railroad began operation and construction was complete, it became the Alaska Railroad Commission, later renamed to The Alaska Railroad. Among other accomplishments, it designed and/or built a number of works listed on the U.S. National Register of Historic Places. Works include: *Mears Memorial Bridge, built in 1923 * Alaska Engineering Commission Cottage No. 23, 618 Christensen Dr. Anchorage, Alaska, NRHP-listed * Alaska Engineering Commission Cottage No. 25, 645 W.

Dual Gauge
In railway engineering, "gauge" is the transverse distance between the inner surfaces of the heads of two rails, which for the vast majority of railway lines is the number of rails in place. However, it is sometimes necessary for track to carry railway vehicles with wheels matched to two different gauges. Such track is described as dual gauge – achieved either by addition of a third rail, if it will fit, or by two additional rails. Dual-gauge tracks are more expensive to configure with signals and sidings, and to maintain, than two separate single-gauge tracks. It is therefore usual to build dual-gauge or other multi-gauge tracks only when necessitated by lack of space or when tracks of two different gauges meet in marshalling yards or passenger stations. Dual-gauge tracks are by far the most common configuration, but triple-gauge tracks have been built in some situations. Background The rail gauge is the most fundamental specification of a railway. Rail tracks and whee ...
