Chapter 2: System and Route Planning

This chapter covers the range of issues which need to be considered when planning a new railway route or system. These issues are grouped under the three main aspects of sustainability: social, environmental and economic, while noting that there are inevitably some overlaps between them. This chapter therefore provides information which can help ensure that a holistic and comprehensive consideration of sustainability is embedded in the planning process. It also discusses how the various impacts associated with the construction and operation of a new railway route or system can be compared and assessed in order to determine whether or not a proposed rail scheme should go ahead.
