Wye (rail)
In railroad structures and rail terminology, a wye (like the'' 'Y' ''glyph) or triangular junction (often shortened to just triangle) is a triangular joining arrangement of three Track (rail transport), rail lines with a railroad switch (set of points) at each corner connecting to the incoming lines. A turning wye is a specific case. Where two rail lines join, or where a spur diverges from a railroad's mainline, wyes can be used at a Junction (rail), mainline rail junction to allow incoming trains to travel in either direction. Wyes can also be used for turning railway equipment, and generally cover less area than a balloon loop doing the same job, but at the cost of two additional sets of points to construct and then maintain. These turnings are accomplished by performing the railway equivalent of a three-point turn through successive junctions of the wye. The direction of travel and the relative orientation of a locomotive or railway vehicle thus can be reversed. Where a wye ...

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, Fuel oil, oil or, rarely, Wood fuel, wood) to heat water in the locomotive's Boiler (power generation), 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 Steam locomotive components, 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 (rail), tender coupled to it. #Variations, 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 of Great Britain an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tecuci
Tecuci () is a city in Galați County, Romania, in the historical region of Western Moldavia. It is situated among wooded hills, on the right bank of the Bârlad River, and at the junction of railways from Galați, Bârlad, and Mărășești. History The area neighboring Tecuci was the scene of a fierce battle in 1476 between Moldavian Prince Stephen the Great and the Ottomans. Under the Kingdom of Romania, it was the residence of the now-defunct Tecuci County. Economy The city was famous for its canned food factories, which preserve vegetables, fruit and meat, as well as for its mustard factories. Climate Climate in Tecuci is defined as Dfb (Humid continental climate with warm summers), bordering a Dfa (Humid continental climate with hot summers). Population As of the 2011 census, there were 34,871 inhabitants who lived within the city limits, of which 83.2% were Romanians Romanians (, ; dated Endonym and exonym, exonym ''Vlachs'') are a Romance language ...

Street-running
A street running train is a train which runs on a Railway track, track built on public streets. The rails are embedded in the roadway, and the train shares the street with other users, such as pedestrians, cars and cyclists, thus often being referred to as running in mixed traffic. Tram and light rail systems frequently run on streets, with light rail lines typically separated from other traffic. For safety, street running trains travel more slowly than trains on dedicated rights-of-way. Needing to share the right-of-way with motor vehicles can cause delays and pose a safety risk. Stations on such routes are rare and may appear similar in style to a tram stop, but often lack platforms, pedestrian islands, or other amenities. In some cases, passengers may be required to wait on a distant sidewalk, and then board or disembark by crossing the traffic. The last street-station in the United States was 11th Street station (Indiana), 11th Street in Michigan City, Indiana, Michigan Ci ...

Electric Locomotive
An electric locomotive is a locomotive powered by electricity from overhead lines, a third rail or on-board energy storage such as a Battery (electricity), battery or a supercapacitor. Locomotives with on-board fuelled prime mover (locomotive), prime movers, such as diesel engines or gas turbines, are classed as Diesel–electric powertrain, diesel–electric or turbine–electric powertrain, gas turbine–electric and not as electric locomotives, because the electric generator/motor combination serves only as a Transmission (mechanics), power transmission system. Electric locomotives benefit from the high efficiency of electric motors, often above 90% (not including the inefficiency of generating the electricity). Additional efficiency can be gained from regenerative braking, which allows kinetic energy to be recovered during braking to put power back on the line. Newer electric locomotives use AC motor-inverter drive systems that provide for regenerative braking. Electric loco ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Push–pull Train
Push–pull is a configuration for locomotive-hauled trains, allowing them to be driven from either end of the train, whether having a locomotive at each end or not. A push–pull train has a locomotive at one end of the train, connected via some form of remote control, such as multiple-unit train control, to a vehicle equipped with a control cab at the other end of the train. This second vehicle may be another locomotive, or an unpowered control car. In the UK and some other parts of Europe, the control car is referred to as a ''driving trailer'' (or driving van trailer/DVT where there is no passenger accommodation); in the US and Canada, they are called ''cab cars'' and in Australia, they are called driving trailers. Train formation Locomotive at one end Historically, push–pull trains with steam power provided the driver with basic controls at the cab end along with a bell or other signalling code system to communicate with the fireman located in the engine itse ...

Tank Locomotive
A tank locomotive is a steam locomotive which carries its water in one or more on-board water tanks, instead of a more traditional tender (rail), tender. Most tank engines also have Fuel bunker, bunkers (or fuel tanks) to hold fuel; in a #Tender-tank, tender-tank locomotive a tender holds some or all of the fuel, and may hold some water also. There are several different types of tank locomotive, distinguished by the position and style of the water tanks and fuel bunkers. The most common type has tanks mounted either side of the boiler. This type originated about 1840 and quickly became popular for industrial tasks, and later for Shunting (rail), shunting and shorter-distance Main line (railway), main line duties. Tank locomotives have #Advantages and disadvantages, advantages and disadvantages compared to traditional locomotives that required a separate tender to carry needed water and fuel.

Balloon Loop
A balloon loop, turning loop, or reversing loop ( North American Terminology) allows a rail vehicle or train to reverse direction without having to shunt or stop. Balloon loops can be useful for passenger trains and unit freight trains. Balloon loops are common on tram and streetcar systems. Many streetcar and tram systems use single-ended vehicles that have doors on only one side and controls at only one end. These systems may also haul trailers with no controls in the rear car, and, as such, must be turned at each end of the route. History Balloon loops were first introduced on tram and, later, metro lines. They did not commonly appear on freight railways until the 1960s, when the modernising British Rail system introduced '' merry-go-round'' (MGR) coal trains that operated from mines to power stations and back again without shunting. Tramways On the former Sydney tram system, loops were used from 1881 until the second-generation system's closure in 1961. Initial ...

Railway Turntable
A railway turntable or wheelhouse is a device for turning railway rolling stock, usually locomotives, to face a different direction. It is especially used in areas where economic considerations or a lack of sufficient space have served to weigh against the construction of a Wye (rail), turnaround wye. Railways needed a way to turn steam locomotives around for return journeys, as their controls were often not configured for extended periods of running in reverse; also many locomotives had a lower top speed in reverse. Most diesel locomotives, however, can be operated in either direction, and are considered to have "front ends" and "rear ends" (often determined by reference to the location of the crew cab). When a diesel locomotive is operated as a single unit, the railway company often prefers, or requires, that it be run "front end" first. When operated as part of a multiple unit locomotive consist, the locomotives can be arranged so that the consist can be operated "front end ...

Circle Line (London Underground)
The Circle line is a spiral-shaped London Underground line, running from Hammersmith in the west to Edgware Road and then looping around central London back to Edgware Road. The railway is below ground in the central section and on the loop east of Paddington. Unlike London's deep-level lines, the Circle line tunnels are just below the surface and are of similar size to those on British main lines. Printed in yellow on the Tube map, the line serves 36 stations, including most of London's main line termini. Almost all of the route, and all the stations, are shared with one or more of the three other sub-surface lines, namely the District, Hammersmith & City and Metropolitan lines. On the Circle and Hammersmith & City lines combined, over 141 million passenger journeys were recorded in 2019. The first section became operational in 1863 when the Metropolitan Railway opened the world's first underground line between Paddington and with wooden carriages and steam locomot ...

London Underground
The London Underground (also known simply as the Underground or as the Tube) is a rapid transit system serving Greater London and some parts of the adjacent home counties of Buckinghamshire, Essex and Hertfordshire in England. The Underground has its origins in the Metropolitan Railway, opening on 10 January 1863 as the world's first underground passenger railway. The Metropolitan is now part of the Circle line (London Underground), Circle, District line, District, Hammersmith & City line, Hammersmith & City and Metropolitan lines. The first line to operate underground electric locomotive, electric traction trains, the City & South London Railway in 1890, is now part of the Northern line. The network has expanded to 11 lines with of track. However, the Underground does not cover most southern parts of Greater London; there are only 33 Underground stations south of the River Thames.
