Railway design takes careful consideration requiring the route, alignment, track structure. materials, turnout, track maintenance and management, track repair and standard and railroad maintenance operations. In the study request, the line speed over a section of a track that is 50 kilometres long is to be improved.


There are also several stations , tunnels and a number of bridges that are present. The line has a power supply for traction trough an overhead line electrification system. The new traffic flow also requires traffic with a heavier axle weight to run that would increase from 20 tonnes to 25 tonnes. With the new traffic flow, tilting trains as well as conventional passenger stopping train will be non stop. The proposal also include the design of a transition curve. The transition curve will run along a straight tract to a curved track and vice versa. The transition curve will allow the trains to shift from one track to the other. The access of the main lines will be required at a minimum speed of 50 kilometres per hour, and about 50 trains are expected to use the track everyday. It is also in the proposal that a new turnout for a freight depot is to be constructed.
The steps and procedures of the track laying and inspection of the survey are the same. Different trackwork may vary with different approaches. With the definition of route surveying, it is composed of all survey operations necessary for the design and construction of engineering works such as railroads. It is associated with the different highway design and construction. ...
