Track structures

Sleepers
Functions:
➡️hold the rails in correct gauge
➡️ act as an elastic medium between the ballast and rail to absorb the blows snd vibrations of moving loads.
➡️ they also add to the longtiudinal and lateral stability of the permanent track on the whole.
➡️ they also provide means to rectify track gemotry during the service life.

Rails
Functions:
➡️ Support the loads of the train and guides their wheel movement.
➡️ Provide a surface with smaller resistance.
➡️ bear the force of the wheels and spread it to sleeper.
➡️ used as track circuit in electrified railways and automatic block segments.

Ballast
Functions:
➡️ for distributing the load from the sleepers to the formations.
➡️For providing draniage.
➡️Gives longtiudinal and lateral stability to the track.
➡️ provide energy absorption for the track
➡️ facilitate the adjustment of track geomotry.
➡️ hold sleppers in place during passage of trains.
