Redgrave (railway Point), British Columbia
Redgrave siding is about west of Golden, and about east of the mid-point of the Connaught Tunnel beneath Rogers Pass, in southeastern British Columbia. Accessible by road in the summer months, the former small railway community is long gone. The highway turnoff is at the Redgrave Rest Area. Overview Redgrave is a Canadian Pacific Railway (CP) siding at Mile 57.3, Mountain Subdivision. Adjacent to the west is Beavermouth (Mile 62.0), and east is Donald (Mile 51.2). Listed as a station 1899–1910, the location was Mile 2,451.2 from Montreal. If it ever served even as a flag stop, by 1930 it was merely a settlement. The siding allowed trains to pass on the single-track route. The name derives from a smallpox outbreak during the transcontinental construction in the 1880s. Victims displayed a red skin rash, and fatalities were buried in Donald. However, mystery surrounded a simple grave marker at the west end of the rail yard bearing the inscription "J McIvor, 1886".

British Columbia
British Columbia (commonly abbreviated as BC) is the westernmost province of Canada, situated between the Pacific Ocean and the Rocky Mountains. It has a diverse geography, with rugged landscapes that include rocky coastlines, sandy beaches, forests, lakes, mountains, inland deserts and grassy plains, and borders the province of Alberta to the east and the Yukon and Northwest Territories to the north. With an estimated population of 5.3million as of 2022, it is Canada's third-most populous province. The capital of British Columbia is Victoria and its largest city is Vancouver. Vancouver is the third-largest metropolitan area in Canada; the 2021 census recorded 2.6million people in Metro Vancouver. The first known human inhabitants of the area settled in British Columbia at least 10,000 years ago. Such groups include the Coast Salish, Tsilhqotʼin, and Haida peoples, among many others. One of the earliest British settlements in the area was Fort Victoria, established ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Donald, British Columbia
Donald is an unincorporated community in the East Kootenay region of southeastern British Columbia. This almost ghost town is on the northeast shore of the Columbia River immediately southeast of the mouth of Marl Creek. The locality, on British Columbia Highway 1, BC Highway 1, is by road about northwest of Golden, British Columbia, Golden and northeast of Revelstoke, British Columbia, Revelstoke. Name origin During railway construction, a lively canvas town with numerous stores and saloons existed. The place was known as Columbia Crossing, First Crossing, or Third Siding. Numbered west from Golden, these sidings housed a platelayer, section crew. On completion of the railway, the station was named after Canadian Pacific Railway (CP) director Donald Smith, 1st Baron Strathcona and Mount Royal, Donald A. Smith. Railway At Donald, CP received a grant and purchased a further . By November 1884, the westward advance of the CP rail head had passed through Donald and reached Beavermo ...

Autorack
An autorack, also known as an auto carrier (also car transporter outside the US), is a specialized piece of railroad rolling stock used to transport automobiles and light trucks. Autoracks are used to transport new vehicles from factories to automotive distributors, and to transport passengers' vehicles in car shuttles and motorail services, such as Amtrak's ''Auto Train'' route. History In the early 20th century, when automobiles were still new technology, their production levels were low enough that they could be shipped in sufficient quantities in boxcars. Two to four automobiles would usually fit into one boxcar. But as the automobile industry grew in size, railroads found that they needed to modify the boxcars for more efficient loading. Some modifications included longer boxcars, larger sliding double side doors located near one end of the boxcar, or doors located on the boxcar ends. These modifications helped, but the demand for new automobiles outpaced the railroads' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hopper Car
A hopper car (US) or hopper wagon ( UIC) is a type of railroad freight car used to transport loose bulk commodities such as coal, ore, grain, and track ballast. Two main types of hopper car exist: covered hopper cars, which are equipped with a roof, and open hopper cars, which do not have a roof. This type of car is distinguished from a gondola car in that it has opening doors on the underside or on the sides to discharge its cargo. The development of the hopper car went along with the development of automated handling of such commodities, with automated loading and unloading facilities. Covered hopper cars are used for bulk cargo such as grain, sugar, and fertilizer that must be protected from exposure to the weather. Open hopper cars are used for commodities such as coal, which can suffer exposure with less detrimental effect. Hopper cars have been used by railways worldwide whenever automated cargo handling has been desired. "Ore jennies" is predominantly a term for shorter ...

Defect Detector
A defect detector is a device used on railroads to detect axle and signal problems in passing trains. The detectors are normally integrated into the tracks and often include sensors to detect several different kinds of problems that could occur. Defect detectors were one of the inventions which enabled American railroads to eliminate the caboose at the rear of the train, as well as various station agents placed along active routes to detect unsafe conditions. The use of defect detectors has since spread overseas to other railroad systems. History Before the advent of automated detectors, on-board train crew and track-side workers used to visually inspect trains for defects e.g. " hotboxes" (overheating bearings) would smoke or glow red. By the 1940s, automatic defect detectors included infrared sensors for hotboxes, wires outlining the clearance envelope to detect high and wide loads, and "brittle bars" – frangible bars mounted between the rails – to detect dragging equip ...

Mica Dam
Mica Dam is a hydroelectric embankment dam spanning the Columbia River 135 kilometres north of Revelstoke, British Columbia, Canada. It was built as one of three Canadian projects under the terms of the 1964 Columbia River Treaty and is operated by BC Hydro. Completed in 1973, the Mica powerhouse had an original generating capacity of 1,805 megawatts (MW). Mica Dam, named after the nearby settlement of Mica Creek and its associated stream, in turn named after the abundance of mica minerals in the area, is one of the largest earthfill dams in the world. The reservoir created by the dam is Kinbasket Lake. Water from the dam flows south directly into Revelstoke Lake, the reservoir for the Revelstoke Dam. Mica Dam is the tallest dam in Canada and second tallest in North America after the Chicoasén Dam in Mexico and it is the farthest upstream dam on the Columbia River. The dam's underground powerhouse was the second largest in the world at the time of its construction, and was the fir ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Columbia River
The Columbia River (Upper Chinook: ' or '; Sahaptin: ''Nch’i-Wàna'' or ''Nchi wana''; Sinixt dialect'' '') is the largest river in the Pacific Northwest region of North America. The river rises in the Rocky Mountains of British Columbia, Canada. It flows northwest and then south into the U.S. state of Washington, then turns west to form most of the border between Washington and the state of Oregon before emptying into the Pacific Ocean. The river is long, and its largest tributary is the Snake River. Its drainage basin is roughly the size of France and extends into seven US states and a Canadian province. The fourth-largest river in the United States by volume, the Columbia has the greatest flow of any North American river entering the Pacific. The Columbia has the 36th greatest discharge of any river in the world. The Columbia and its tributaries have been central to the region's culture and economy for thousands of years. They have been used for transportation since a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Platelayer
A platelayer (British English), fettler (British English – UK, Australia, NZ) or trackman (American English) is a railway employee who inspects and maintains the permanent way of a railway, usually under the charge of a foreman called (in UK, Australia and NZ) the "ganger". The term "platelayer" derives from the plates used to build plateways, an early form of railway. Track inspection Inspecting and maintaining the track, including all its component parts such as rails, sleepers, fishplates, bolts, etc., are the chief responsibility of the platelayer. Their duties include greasing points, and generally watching for wear and tear. When sections of track require complete replacement, larger teams of platelayers work together, and today employ a range of labour-saving machinery for many of the tasks traditionally undertaken by hand by platelayers. Platelayers' hut United Kingdom In British usage the term ''platelayers' hut'' refers to a lineside shelter in which a platel ...

CPR Redgrave Tunnel 1899
Cardiopulmonary resuscitation (CPR) is an emergency procedure consisting of chest compressions often combined with artificial ventilation in an effort to manually preserve intact brain function until further measures are taken to restore spontaneous blood circulation and breathing in a person who is in cardiac arrest. It is recommended in those who are unresponsive with no breathing or abnormal breathing, for example, agonal respirations. CPR involves chest compressions for adults between and deep and at a rate of at least 100 to 120 per minute. The rescuer may also provide artificial ventilation by either exhaling air into the subject's mouth or nose (mouth-to-mouth resuscitation) or using a device that pushes air into the subject's lungs (mechanical ventilation). Current recommendations place emphasis on early and high-quality chest compressions over artificial ventilation; a simplified CPR method involving only chest compressions is recommended for untrained rescuers.

Smallpox
Smallpox was an infectious disease caused by variola virus (often called smallpox virus) which belongs to the genus Orthopoxvirus. The last naturally occurring case was diagnosed in October 1977, and the World Health Organization (WHO) certified the global eradication of the disease in 1980, making it the only human disease to be eradicated. The initial symptoms of the disease included fever and vomiting. This was followed by formation of ulcers in the mouth and a skin rash. Over a number of days, the skin rash turned into the characteristic fluid-filled blisters with a dent in the center. The bumps then scabbed over and fell off, leaving scars. The disease was spread between people or via contaminated objects. Prevention was achieved mainly through the smallpox vaccine. Once the disease had developed, certain antiviral medication may have helped. The risk of death was about 30%, with higher rates among babies. Often, those who survived had extensive scarring of their ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Single-track Railway
A single-track railway is a railway where trains traveling in both directions share the same track. Single track is usually found on lesser-used rail lines, often branch lines, where the level of traffic is not high enough to justify the cost of constructing and maintaining a second track. Advantages and disadvantages Single track is significantly cheaper to build and maintain, but has operational and safety disadvantages. For example, a single-track line that takes 15 minutes to travel through would have capacity for only two trains per hour in each direction safely. By contrast, a double track with signal boxes four minutes apart can allow up to 15 trains per hour in each direction safely, provided all the trains travel at the same speed. This hindrance on the capacity of a single track may be partly overcome by making the track one-way on alternate days, if the single track is not used for public passenger transit. Long freight trains are a problem if the passing s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Request Stop
In public transport, a request stop, flag stop, or whistle stop is a stop or station at which buses or trains, respectively, stop only on request; that is, only if there are passengers or freight to be picked up or dropped off. In this way, stops with low passenger counts can be incorporated into a route without introducing unnecessary delay. Vehicles may also save fuel by continuing through a station when there is no need to stop. There may not always be significant savings on time if there is no one to pick up because vehicles going past a request stop may need to slow down enough to be able to stop if there are passengers waiting. Request stops may also introduce extra travel time variability and increase the need for schedule padding. The appearance of request stops varies greatly. Many are clearly signed, but many others rely on local knowledge. Implementations The methods by which transit vehicles are notified that there are passengers waiting to be picked up at a reque ...
