This is to facilitate the construction of a turnout on a section that is straight. The construction of the curve is to allow access for freight traffic converge into a new intermodal freight depot and access of the main lines will be required at a minimum speed of 50 kilometres per hour and 50 trains will be expected to use the railroad track everyday. A track handbook must be discussed with the railway staff senior officer for a suitable turnout for the traffic usage and speed.
By definition, route surveying is composed of all survey operations needed for the design and construction of the engineering works such as railroads. The system of a route surveying is associated with design of a highway and its construction. This contains four separate and inter related processes. Reconnaissance and planning is the first in the inter related process. Reconnaissance in the method of gathering of the possible data found in the area. Planning is the method of preparation of all the work to be done. The design of the improvements of the projects are then worked out for the implementation. Transportation infrastructure and the other major projects requires the taking of real properties, or right-of-way. The would be cost of the partial takings, commercial properties, remainder damages, court costs, utility relocations and other related right-of-way items are very difficult to anticipate. Accuracy in the estimate procedures are used to facilitate the budgeting and timely completion of the projects. The construction work is the actual implementation of all the processes which takes from reconnaissance and planning.
Components required for the route improvement
The centreline of the railroad track is the reference point used in railroad surveys. This is stationed at 20 metres chord in curves, and stations have references at valuation points. The stationing is one of the components of the route improvement of the railroad track. The route is to have stations in order to determine the locations of obstructions along the route of work. The offset distance is the specified line or curve. This is implemented as a pair of 2lines or curves that are of equal distance from the point of original line or curve. Profile grade is a vertical alignment required for all roadway or computation of the track design. The vertical alignment data is provided for the description of the alignment in the design. Vertical curves are required at any intersection of different road/rail gradients. The design are done so that the rate of change of the vertical acceleration is gradual for the safety and comfort of the commuters and the incoming vehicle would be visible for a safe distance. The horizontal curves are used to change the alignment, and direction or the slope of a railroad. Curves that change the alignment are called the horizontal curves Offset stakes are used primarily to catch point and will produce a slope stake information. The location of the slope stake is dependent to the position of the pivot point where the slope begins. Slope stakes are used in highways and track works for the location of the toe of slope or the top of the cut.
The economic and environmental arguments for the expanded railway network had the support from the
