Rails Of The Railway

Comments Off on Rails Of The Railway

The rails are the elements that play the more prominent role from the point of view of safety in transportation by rail. Within the superstructure, corresponding annual investments may affect 3-7% of the total length of the railway networks, still above this figure for metropolitan railways. Features of Rails that make up the railroad tracks on which the railways, scroll are the absorb and transmit efforts, guide to trains and circulating material, and serve as a conductive element to electricity.

These efforts can be vertical, transversal and longitudinal.

Vertical forces transmitted by the Rails to the ground come from the self weight of the railways and circulating material, with its possibility of unequal distribution of the overloads due to uncompensated centrifugal force (quasi-static loads), and overloads due to the action of the masses not suspended and suspended vehicles by irregularities of the pathway or material, such as unevenness, ovalaciones, flat wheels, or oscillations of the vehicle itself (dynamic loading). Among cross-cutting efforts that must absorb the lanes is the action of centrifugal force not compensated, as well as the transverse component of the forces caused by the motion. Longitudinal rails efforts are mainly those of thermal origin, although the longitudinal component of the effort created by the movement of loop, or effects due to intense accelerations of starting and braking can also be important. Railway rails should guide the circulating material with maximum continuity, both plant and elevation. Rails, also, serve as conductive elements for the return of power to those exploited in electric traction railway lines, as well as the signalling currents, when track circuits are used.
