Railway turnout is a mechanical device that used to guide the trains from one rail track to another. As an important part in rail construction, turnout helps to enable the trafficability of the rail.
What is light rail transportation?
Light-rail transit (LRT) is rapid transit that operates electric-powered single cars or short trains on fixed rails. Light refers to lighter passenger capacity, not the physical weight of the vehicles. LRT service addresses a gap between local buses and heavy rail.
How do light rail vehicles work?
Light rail vehicles are typically driven electrically with power being drawn from an overhead electric line via a trolley [pole] or a pantograph; driven by an operator onboard the vehicle; and may have either high platform loading or low-level boarding using steps.”
What is difference between turnout and crossover?
A Variety of Turnouts Basic types of turnouts include a “Single turnout” that diverges one rail track into two directions, a “Diamond crossing” that intersects two tracks,and a “Crossover” that connects two side-by-side tracks.
What is the meaning of turnouts?
Definition of turnout (Entry 1 of 2) 1 : the number of people who participate in or attend an event a heavy voter turnout. 2a : a place where something (such as a road) turns out or branches off. b : a space adjacent to a highway in which vehicles may park or pull into to enable others to pass.
What is the purpose of turnout?
A railroad switch ( AE ), turnout, or [set of] points ( BE ) is a mechanical installation enabling railway trains to be guided from one track to another, such as at a railway junction or where a spur or siding branches off.
What is light rail vs heavy rail?
In North America, the American Public Transportation Association defines a heavy-rail system as an electric railway with the capacity to handle a heavy volume of traffic. The term is often used to distinguish it from light rail systems, which usually handle a smaller volume of passengers.
Is light rail rapid transit?
Light rail, monorail, and Bus Rapid Transit are all forms of rapid transit, which generally signifies high speed and widely-spaced stops. Trams are a form of local transit, making more frequent stops.
Is light rail better than buses?
In terms of operating costs, it is often argued that light rail is cheaper to operate than buses because the capacity of light rail is so much greater than buses. If there is enough demand along a corridor to operate buses every two minutes, then a light rail train would have lower operating costs than buses.
What is a crossover in rail?
A Crossover is a pair of complementing Turnouts linked by common Closure Rails. They allow a transition between two parallel tracks.
What are turnouts in irrigation?
A “turnout” or “offtake” or “delivery gate” is the point at which the control of the water changes from the irrigation district to the customer(s). Turnout Functions.
What are the different types of turnouts in a railroad?
Turnouts. Turnouts and crossovers, including switches, frogs, guard rails, stock rails, and closure rails; rail fastening assemblies unique to turnouts; and miscellaneous components associated with turnouts, including switch rods and gauge plates. Crossover tracks, double crossovers including the central crossing frogs or diamond area,…
What are the stock rails on a turnout switch?
Turnouts. Stock rails are the running rails immediately alongside of the switch rails against which the switch rails lay when in the closed position. The stock rails are otherwise ordinary rails that are machined, drilled, and bent as required to suit the design of the turnout switch and the individual switch point rails.
What is a lapped turnout and how does it work?
In a lapped turnout, as seen in following picture, the switch rails for a second turnout will be placed between the switch and the frog of the initial turnout. This introduces a third frog where a closure rail of the first turnout crosses a closure rail of the second turnout.
Where are the operating devices located in a railway turnout?
In both cases, the operating devices are positioned at the beginning of the railway turnout opposite the switch-connecting rods near the point of the switch rails. A single crossover consists of two railway turnouts positioned in two tracks that allow the vehicle to go from one track to another.
