TC-117
The DOT-117 (TC-117 in Canada) is a type of unpressurized tank car in use on North American railroads. The DOT-117 design was developed in the aftermath of the Lac-Mégantic rail disaster of 2013 in an effort to upgrade the specifications of the then-common DOT-111 and CPC-1232 designs. It was announced on May 1, 2015 by the United States Federal Railroad Administration (FRA) and Canada's Transport Canada (TC). The specifications require that the tank shells be constructed out of steel Steel is an alloy made up of iron with added carbon to improve its strength and fracture resistance compared to other forms of iron. Many other elements may be present or added. Stainless steels that are corrosion- and oxidation-resistant ty ..., with 11-gauge () sheet metal jackets, thick head shields on the ends of the tanks, and improved valves over previous designs. In order to implement the DOT-117 standard, the FRA and TC required that all new tank cars constructed after October 1, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lac-Mégantic Rail Disaster
The Lac-Mégantic rail disaster occurred in the town of Lac-Mégantic, Quebec, Canada, on July 6, 2013, at approximately 01:15 EDT, when an unattended 73-car Montreal, Maine and Atlantic Railway (MMA) freight train carrying Bakken Formation crude oil rolled down a 1.2% grade from Nantes and derailed downtown, resulting in the explosion and fire of multiple tank cars. Forty-seven people were killed. More than thirty buildings in Lac-Mégantic's town centre, roughly half of the downtown area, were destroyed, and all but three of the thirty-nine remaining buildings had to be demolished due to petroleum contamination of the townsite. Initial newspaper reports described a blast radius. The Safety Board identified multiple causes for the accident, principally leaving a train unattended on a main line, failure to set enough handbrakes, and lack of a backup safety mechanism. The death toll of 47 makes this the fourth-deadliest rail accident in Canadian history, and the deadliest in ... [...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 ...

DOT-111 Tank Car
In rail transport, the U.S. DOT-111 tank car, also known as the TC-111 in Canada, is a type of unpressurized general service tank car in common use in North America. Tank cars built to this specification must be circular in cross section, with Ellipsoid, elliptical, Forming (metalworking), formed heads set convex outward. They have a minimum plate thickness of and a maximum capacity of . Tanks may be constructed from carbon steel, aluminum alloy, Alloy steel, high alloy steel, or Nickel electroplating, nickel plate steel by fusion welding. Usage Up to 80% of the Canadian fleet and 69% of U.S. rail tank cars were DOT-111 type, as of 2013. DOT-111 cars are equipped with AAR Type E top and bottom shelf Janney couplers designed to maintain vertical alignment to prevent couplers from overriding and puncturing the tank end frames in the event of an accident. These tank cars transport various types of liquid dangerous goods, including 40,000 cars in dedicated service carrying 219,000 c ...

Federal Railroad Administration
The Federal Railroad Administration (FRA) is an agency in the United States Department of Transportation (DOT). The agency was created by the Department of Transportation Act of 1966. The purpose of the FRA is to promulgate and enforce rail safety regulations, administer railroad assistance programs, conduct research and development in support of improved railroad safety and national rail transportation policy, provide for the rehabilitation of Northeast Corridor rail passenger service, and consolidate government support of rail transportation activities. The FRA is one of ten agencies within DOT concerned with intermodal transportation. It operates through seven divisions under the offices of the Administrator and Deputy Administrator. These divisions are: Financial Management and Administration, Chief Counsel, Civil Rights, Public Affairs, Public Engagement, Railroad Policy and Development, and Safety. It has a staff of about 850. Function All passenger and freight rail ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Transport Canada
Transport Canada (french: Transports Canada) is the department within the Government of Canada responsible for developing regulations, policies and services of road, rail, marine and air transportation in Canada. It is part of the Transportation, Infrastructure and Communities (TIC) portfolio. The current Minister of Transport is Omar Alghabra. Transport Canada is headquartered in Ottawa, Ontario. History The Department of Transport was created in 1935 by the government of William Lyon Mackenzie King in recognition of the changing transportation environment in Canada at the time. It merged three departments: the former Department of Railways and Canals, the Department of Marine, and the Civil Aviation Branch of the Department of National Defence (c. 1927 when it replaced the Air Board) under C. D. Howe, who would use the portfolio to rationalize the governance and provision of all forms of transportation (air, water and land). He created a National Harbours Board and Trans-C ...

Steel
Steel is an alloy made up of iron with added carbon to improve its strength and fracture resistance compared to other forms of iron. Many other elements may be present or added. Stainless steels that are corrosion- and oxidation-resistant typically need an additional 11% chromium. Because of its high tensile strength and low cost, steel is used in buildings, infrastructure, tools, ships, trains, cars, machines, electrical appliances, weapons, and rockets. Iron is the base metal of steel. Depending on the temperature, it can take two crystalline forms (allotropic forms): body-centred cubic and face-centred cubic. The interaction of the allotropes of iron with the alloying elements, primarily carbon, gives steel and cast iron their range of unique properties. In pure iron, the crystal structure has relatively little resistance to the iron atoms slipping past one another, and so pure iron is quite ductile, or soft and easily formed. In steel, small amounts of carbon, other ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sheet Metal
Sheet metal is metal formed into thin, flat pieces, usually by an industrial process. Sheet metal is one of the fundamental forms used in metalworking, and it can be cut and bent into a variety of shapes. Thicknesses can vary significantly; extremely thin sheets are considered foil or leaf, and pieces thicker than 6 mm (0.25 in) are considered plate, such as plate steel, a class of structural steel. Sheet metal is available in flat pieces or coiled strips. The coils are formed by running a continuous sheet of metal through a roll slitter. In most of the world, sheet metal thickness is consistently specified in millimeters. In the U.S., the thickness of sheet metal is commonly specified by a traditional, non-linear measure known as its gauge. The larger the gauge number, the thinner the metal. Commonly used steel sheet metal ranges from 30 gauge to about 7 gauge. Gauge differs between ferrous ( iron-based) metals and nonferrous metals such as aluminum or copper. Cop ...

Rolling Stock Of Canada
Rolling is a type of motion that combines rotation (commonly, of an axially symmetric object) and translation of that object with respect to a surface (either one or the other moves), such that, if ideal conditions exist, the two are in contact with each other without sliding. Rolling where there is no sliding is referred to as ''pure rolling''. By definition, there is no sliding when there is a frame of reference in which all points of contact on the rolling object have the same velocity as their counterparts on the surface on which the object rolls; in particular, for a frame of reference in which the rolling plane is at rest (see animation), the instantaneous velocity of all the points of contact (e.g., a generating line segment of a cylinder) of the rolling object is zero. In practice, due to small deformations near the contact area, some sliding and energy dissipation occurs. Nevertheless, the resulting rolling resistance is much lower than sliding friction, and thus, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
