Holistic capacity of rail networks: exposing asset deficiencies in a complex system

The demand for additional rail capacity has been tempered by concerns over the magnitude of required investment levels. New tools for holistic analysis of the rail network can reveal the simulated network ‘pinch points’ before they become practical reality. Individual decisions on service frequency, axle load, signalling systems, power supplies, train type and length, track layout, rolling stock selection, braking and acceleration rates etc. impact network rail and energy capacity. Failure to make the correct infrastructure decisions can result in damaging rectification cost burdens to both operators and asset owners. This paper demonstrates how Queensland Rail established a bench mark ‘Proof of Concept’ test to prove that simulation software could reproduce ‘holistically’, the daily activities of the suburban Cleveland Line. Comparative results from measured single train runs and results of simulated and actual train running and energy consumption over a 5 day morning peak period were better than the benchmark criteria. The test results highlighted limitations with the existing Cleveland line infrastructure that will need to be addressed in any project designed to satisfy increased customer service levels.
