Pages 15 (3765 words)
Rail transport is increasingly becoming important in each and every passing day. The reason being that it eases the congestion in major towns and cities. Due to the ever increasing population, urbanization and demand for transport of goods and services, the demand for rail transport is on the increase…
The design issue under consideration includes route surveying, track component identification, designing the rail curve and other design aspects that help in improving rail transport. Suggestion indicated can be implemented by any train organization seeking to improve or optimize there services (Mundrey, 1993).
Rail tracks are used for the guidance of trains, and consist of two steel rails laid in parallel. The rails guide the train in motion without the need for steering. The rails are laid on sleepers. The sleeper are also referred to as the cross ties. The sleepers are embedded in the ballast and form the rail road track. The rails are fastened to the sleeper by the use of spikes, lag screws, bolts clips and pandrol clips. The type of fastening sleepers depends on the type of sleepers. For the concrete sleepers clips are used, for the wooden sleepers' spikes are used and for steel sleepers, bolts are commonly used.
Convectional rail design involved route surveying and finding the most economical route for the rail line. The engineer worked on ways of designing the rail so as to surpass the geographical obstacles (Engineering Policy Group (EPG). 2009).
Currently rail design encompasses many design aspects. These design aspect results from the need for greater speeds and heavy loads. ...
