Route selection criteria for a new railway

The decision to introduce a new railway line is influenced by any number of political, social or economic factors. The new line may be required to carry freight, thereby alleviating traffic from already congested roads, or passengers to meet the growing demands of new population centres. Whatever the driver that instigates the requirement, the principles and process of deciding the route alignment are essentially the same, although criteria will be different. The reasons for selecting a particular route alignment should be based on sound engineering principles, whilst ensuring that construction and future operational/maintenance issues have been incorporated. This paper identifies the key route selection criteria that should be considered at the feasibility stage, where minor changes through appropriate engineering evaluation can provide major benefits further into the project. The balance of the railway's key drivers, the environmental and social impacts that the new line may incur are discussed, with some typical mitigation measures outlined. The correct use of a cost benefit analysis model for the evaluation of engineering, environmental, social and economic issues is discussed. Aimed at both engineers and non-engineers included within the decision making process, this paper provides an invaluable insight into the tools and principles used to define the route alignment for a new railway line.
