Brackets for rails

Any device used to secure rails on chairs or base plates or directly to sleepers, brackets or other rail supports. The rail fastening keeps the rails fastened to the sleepers (transfer of forces), provides adequate slope of the rail foot (1:20, 1:40) in the transverse plane, prevents the rail from moving longitudinally, dampens the noise And vibrations from the rails.
General requirements for rail fasteners
Rail fasteners shall:
1. Hold the rails firmly on the rail seat.
2. limit the rotation of the rail around ....etc

A STUDY ON WEAR AND EROSION PROPERTIES OF RAIL STEEL



Introduction:
Steels represent the most important group of engineering materials as they have the widest diversity of applications of any of the engineering materials. Generally, carbon is the most important element profoundly affecting the mechanical properties of the steels. The term steel is used for many different alloys of iron. These alloys vary both in the way they are made and in the proportions of the materials added ....etc

literature survey of air compressor using pedal power air compressor

Abstract

This paper describes a new approach to design and fabrication of Pedal operated air compressor with the goal of building a working prototype. Here is a try to create a mechanical device that can use the mechanical power operated by pedals as in bicycles to run an air compressor and additional water pump. The additional cooling system is used for maintaining the temperature of compressed air. We used a cycle chain-sprocket system as a basic pedaling power source and ....etc

A mechanism is a simplified model, usually in the form of a line diagram, which is used to reproduce the movement occurring in a machine. The purpose of this reproduction is to allow the nature of the machine. The purpose of this reproduction is to allow the nature of the movement to be investigated without the imposition of the various solid bodies forming the machine elements. The various parts of the mechanism are called links or elements. An arbitrary set of couplings forming a Closed which is capable of relative ....etc

A Metro can be either underground or elevatedand in case of outskirts of the cities on theground even.

Metros can be :-

Heavy capacity with a capacity of 60-90,000 phpdt.

Medium capacity with a capacity of 40-50,000phpdt, or,

A light metro with the capacity ranging from 25-30,000 phpdt.

When the traffic volume exceeds 12,000 phpdtit can be handled only by a rail-based MetroSystem.

Metros can be either with pneumatic wheels orsteel wheels on steel rails. In either case thetraction is by electric energy ....etc
