this is because sleepers increase the area on which pressure of train is to be exerted.Thus pressure is not concentrated on a single point densely.therefore if there more area there would be less pressure and train will run smoothly

Why are electromagnets useful in motors?
Electromagnets are sometimes more useful because they can be turned on and off at will. This feature allows them to do things that other permanent magnets cannot do. High speed mag-lev trains use this ability to their advantage to propel themselves down the rails.
Why do high speed trains slow down when they pass each other?
in case the speed they are traveling causes them to collide or rock against each other and scrape
What holds down the rails on railroad track?
Railroad spikes are pounded into the railroad ties and the head of the spike catches the side of the rail. As well, the rail-tie combination is held in place by ballast, consisting of gravel, crushed stone or aggregate on a well packed road bed. .
How is the speed of high speed train controlled?
Most high speed trains are electrically driven, deriving power from an overhead rail via a pantograph. The train has considerable aerodynamic drag, so that if drive to the wheels is reduced, it will slow down. Thus, if you add power it goes faster, if you reduce power it slows down. This can be done manually, or by a computer.
What is the purpose of the coils under a refrigerator?
The purpose of the coils under a refrigerator are to allow the refrigerant to cool down before being turned back into a liquid. This allows the compressor to function properly.
What is the definition of the Railroad?
Steel rails laid and pinned down on ties embedded in gravel so that trains may run on them.
Why stones are put in railway track?
The stones placed in and around railway tracks are technically called `ballast'. The railway track, named `Permanent Way' in rail lingo, is a multi-entity structure which comprises the pair of rail lines running parallel, the spaced sleepers, the ballast and the formation.The force exerted by the wheels of the train is transmitted successively in a proportionally diminishing extent down the rails, the sleepers and the ballast to the formation, a well prepared and consolidated road bed.
Are the tube lines in London always electricified?
No the traction rails (not the ones the trains wheels run on) are discharged at the end of passanger service so that engineers can work down the tunnel at night. The traction rails have 600v DC running through them hence the need to discharge at night to prevent electric shock.
What kept trains from being efficient although they were invented long ago?
Trains both were and are very efficient means of transportation, both for freight and passengers. However following WW2 the car companies and the oil companies decided to shut down all existing commuter trains to increase their profits, they bought up the lines and either switched them to diesel buses or simply shut them down and selling the steel rails as scrap. Later these same companies lobbied Congress to subsidize highways and the airlines, stealing much long distance business from the railroads.Without the funds to maintain the rails properly speeds had to be reduced, making trains look even less attractive to potential customers.

What is the foundation for the rails and ties of a railroad?
The ballast is set in a graded bed. The graded soil must be level to set the rails and ties. Gravel, or ballast, is laid between the ties and rails, and tamped down.
Where did the railroad get its name?
it's simple. The rails in the railroad was layed down on a road.
Is a bullet train as fast as a electromagnetic train?
if your talking about the monorail V bullit train then probably not, the reason being the bullit train is on the normal tracks whil the monorail trains are floating so there is no friction between the train cars & the rails. even speed comes down to friction
Does the back bench seat of a 1999 mercury village estate come out?
It comes out if you remove the 2 bolts in front and 4 bolts in back. But you are left with the brackets sticking up from the rail sliders. There are bolts down the sides of the rails, under the carpet if you want to remove the whole works, but then you are left with a gulley where the rails were.
How do you jump the acro bike in vba?
Press X & Up or down at the same time and it will jump on the rails :)
What are the Lyrics to Country rock song that has somthing like going down to the railroad tracks?
On the rails with Joe Ely
How do you bike on rails in Pokemon emerald?
You need the Acro bike, not the Mach bike. To rid on straight rails just go foreward.To jump to paralel rails, pres the direction you want to hop and B(or prehaps A, it has been a while) at the same time. To cross other gaps, bunny hop by holding down B.
