Railway Survey | New Railway Line Survey

Prior to survey the available maps of proposed area are studied. This helps in fixing suitable alignment facilitate various surveys work. The various engineering surveys which are carried out for the choice of route of a new railway line can broadly be divided in to three categories Reconnaissance Survey, Preliminary Survey and Location Survey

creep in rail

Magnitude and Direction of Creep

Creep is not constant over a given period, it is not continue in one direction or at uniform rate. Both the rails of the track may creep in same direction, perhaps both the rails reverse the direction of creep or one rail creep in opposite direction to that of other. In other words, the direction and magnitude of creep cannot be predicted.

construction of railway track

Construction of Railway Track Methods

There are three distinct methods of construction of railway track. These are: Telescopic Method, Tramline Method & Mechanical Method. Telescopic method, rails, sleepers and fastenings are unloaded from the material train as close to the rail head as possible. The sleepers are carried by carts or men along the adjoining service road and spread on the ballast.
