Mullan Pass
Mullan Pass is a mountain pass in the western United States, in the Rocky Mountains of Montana. It sits on the Continental Divide on the border between Powell and Lewis and Clark counties at 5,902 feet (1,799 m) above sea level. Located in the Helena National Forest, the pass is thirteen miles (20 km) west of the city of Helena. The Northern Pacific Railway (NP) used the pass for its line from Logan to Garrison via Helena, built in 1883. This line was the NP's primary freight route and was also used by their secondary passenger train, the '' Mainstreeter''. The NP also built an alternate line over Homestake Pass, which was used by their primary passenger train, the ''North Coast Limited''. The rail line at Mullan Pass is currently operated by Montana Rail Link; it crosses under the pass and the continental divide at via the Mullan Tunnel. The pass was named after Lieutenant John Mullan, the U.S. Army engineer who first crossed the pass on March 22, 1854, and lat ...

North Coast Limited
The ''North Coast Limited'' was a List of named passenger trains, named passenger train operated by the Northern Pacific Railway between Chicago and Seattle via Bismarck, North Dakota. It started on April 29, 1900, and continued as a Burlington Northern Railroad train after the merger on March 2, 1970 with Great Northern Railway (U.S.), Great Northern Railway and the Chicago, Burlington and Quincy Railroad. The next year, it ceased operations after the trains which left their originating stations on April 30, 1971, the day before Amtrak began service (May 1, 1971), arrived at their destinations. After 1918 the Chicago to St. Paul leg of the route was on the Chicago, Burlington and Quincy railroad along its Mississippi River line through Wisconsin. The train had a Portland section which split off the Seattle section at Pasco, Washington and ran over NP subsidiary Spokane, Portland and Seattle Railway between Pasco and Portland. For much of its history the ''North Coast Limited' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lookout Pass
Lookout Pass is a mountain pass in the Rocky Mountains of the northwestern United States. In the Coeur d'Alene Mountains of the Bitterroot Range, the pass is on the border between Idaho and Montana, traversed by Interstate 90 (formerly U.S. Route 10) at an elevation of above sea level. Lookout Pass is the eastern border of northern Idaho's Silver Valley, and has the distinction of being "Exit 0" on Interstate 90 in Montana. Established in 1935, Lookout Pass Ski and Recreation Area is on the eastbound side of the highway, straddling the border. The state border line is the ridge line of the mountains and at the pass runs briefly east–west, with Idaho on the north side and Montana the south. The pass separates the communities of Mullan in Shoshone County, Idaho, and Saltese in Mineral County, Montana. It is the highest point on Interstate 90 between Seattle and Missoula. The pass is also a time zone border, with northern Idaho on Pacific Time and Montana on Mounta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bitterroot Range
The Bitterroot Range is a mountain range and a subrange of the Rocky Mountains that runs along the border of Montana and Idaho in the northwestern United States. The range spans an area of and is named after the bitterroot (''Lewisia rediviva''), a small pink flower that is the state flower of Montana. History In 1805, the Corps of Discovery, led by Meriwether Lewis and William Clark and aided by Sacajawea of the Shoshone Native American tribe, crossed the Bitterroot Range several times. Lewis first crossed the mountains at Lemhi Pass on August 12, then returned across the pass to meet Clark. The entire expedition then crossed the pass to the Salmon River valley, and the next month entered the Bitterroot Valley from the south via either Lost Trail Pass or Chief Joseph Pass. It then crossed Lolo Pass to the west. The mountains were crossed by the Chicago, Milwaukee, St. Paul and Pacific Railroad (the "Milwaukee Road"). Ranges According to the U.S. Board on Geographic ...

Double-stack Rail Transport
Double-stack rail transport is a form of intermodal freight transport in which railroad cars carry two layers of intermodal containers. Invented in the United States in 1984, it is now being used for nearly seventy percent of United States intermodal shipments. Using double stack technology, a freight train of a given length can carry roughly twice as many containers, sharply reducing transport costs per container. On United States railroads special well cars are used for double-stack shipment to reduce the needed vertical clearance and to lower the center of gravity of a loaded car. In addition, the well car design reduces damage in transit and provides greater cargo security by cradling the lower containers so their doors cannot be opened. A succession of larger container sizes have been introduced to further increase shipping productivity in the United States. Double-stack rail operations are growing in other parts of the world, but are often constrained by clearance and ot ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hydrogen Peroxide
Hydrogen peroxide is a chemical compound with the formula . In its pure form, it is a very pale blue liquid that is slightly more viscous than water. It is used as an oxidizer, bleaching agent, and antiseptic, usually as a dilute solution (3%–6% by weight) in water for consumer use, and in higher concentrations for industrial use. Concentrated hydrogen peroxide, or " high-test peroxide", decomposes explosively when heated and has been used as a propellant in rocketry. Hydrogen peroxide is a reactive oxygen species and the simplest peroxide, a compound having an oxygen–oxygen single bond. It decomposes slowly when exposed to light, and rapidly in the presence of organic or reactive compounds. It is typically stored with a stabilizer in a weakly acidic solution in a dark bottle to block light. Hydrogen peroxide is found in biological systems including the human body. Enzymes that use or decompose hydrogen peroxide are classified as peroxidases. Properties The boiling poi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tank Car
A tank car ( International Union of Railways (UIC): tank wagon) is a type of railroad car (UIC: railway car) or rolling stock designed to transport liquid and gaseous commodities. History Timeline The following major events occurred in the years noted: *1865: Flatcars with banded wooden planks or decking mounted on top are employed for the first time to transport crude oil from the fields of Pennsylvania during the Pennsylvanian oil rush. Laurence Myers of Philadelphia invented the ''Rotary Oil Car'', as he named it. It was an improvement on a patent from 1851 of a freight car for transporting coal. The new invention patented on July 18, 1865, was for the transportation of crude oil and petroleum. It was the first appearance of an oil tank on a railroad flatcar. Three books mention his invention. *1869: Wrought iron tanks, with an approximate capacity of per car, replace wooden tanks. *1888: Tank-car manufacturers sell units directly to the oil companies, with capaciti ...

1989 Helena Train Wreck
The Helena Train Wreck occurred in the early morning on February 2, 1989, in Helena, Montana, United States, when 49 cars of a Montana Rail Link freight train that had been decoupled from their locomotives by a train crew on Mullan Pass rolled backwards down the pass, traveling nine miles back into the city of Helena and colliding with a work train at a railway crossing near the center of the community. The collision resulted in a fire and explosion that damaged Carroll College and other nearby structures, knocked out power to most of the town, and led to the evacuation of residents within an area of due to concerns of possible toxic chemical release. The event occurred during a severe cold snap, with temperatures below that morning and with a wind chill factor of as much as , which froze the water that firefighters used to attempt to extinguish the fire. Event In the early morning of February 2, 1989, during a record cold snap, a Montana Rail Link freight train picked u ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cromwell Dixon
Cromwell Dixon (July 9, 1892 – October 2, 1911) was a teenage dirigible pilot and aviator. He became the first person to fly an airplane across the Continental Divide in September 1911 when he flew fifteen miles over Mullan Pass. Life Early life Cromwell Dixon was born in San Francisco July 9, 1892, to Annie and Charles P. Dixon. His father died the next year. With another child on the way, Annie moved to Columbus, Ohio, where she kept her little family together and made a living by renting out rooms and taking in sewing. From an early age, Dixon showed a knack for mechanics. A family story said that he took a clock apart when he was only one year old. As a boy, he built clockwork-powered toys—a fish and a small boat that he sailed on a lake. At the age of ten, Dixon invented a roller coaster for the neighborhood kids; in 1903 he built his own motorcycle. Local newspapers took an interest in Dixon's inventions and began publishing articles about the young inventor by the t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
