Paris RER versus Sydney heavy rail: potential for harbour crossing based on sector complexity

Complex railways can improve operational simplicity through sectorisation. Projects such as Sydney Clearways have separated the operation of one line from another to improve reliability, which in turn increases capacity. However sector definitions are arbitrary. To achieve perfect sectorisation (the separation of sectors) one need only to define very wide, broad sweeping ‘sectors’. To avoid this, and to consider real network capacity and reliability potential, internal sector complexity should also be considered. That is, the complexity contained or hidden within a defined operational sector. This paper considers a technique for examining the operational complexity within a given sector. A key benefit of this approach is to allow the comparison between networks independently of technology such as ATP, signalling, and single vs. double deck rolling stock. This paper also considers the potential of the harbour crossing in Sydney by examining the Paris RER, which demonstrates comparable operational complexity. This case study allows for better understanding of the potential for Sydney if technology upgrades were made to signalling or rolling stock.
