With larger, heavier trams being introduced to Melbourne’s tram network, the older rolling stock is being retired and newer, existing rolling stock is being reassigned to different routes. Before implementing this cascade plan, Public Transport Victoria (PTV) and Yarra Trams wanted to evaluate its effects on operational performance and the current traction power network.
LTK was tasked with building the scenario model and running simulations to quantify these effects and develop upgrade plans.
LTK built the entire Melbourne tram network model using our proprietary rail network modelling tool, TrainOps® and used it to investigate the effect of the tram cascade on the traction power network.
Proposed traction power upgrades (including new substations and additional parallel feeders) were built into the model and tested via simulation scenarios.
First order substation failure (N-1) scenarios were modelled to investigate the resilience of the proposed system upgrades. The simulation results were then presented to the client to identify the priority of the proposed upgrades, renewal or replacement of the existing infrastructure.
Accurate and relevant simulation results allowed PTV to optimise its network upgrade solutions to address the rolling stock cascade in the most efficient manner, reducing the overall cost of infrastructure upgrades and enabling capital investment to be spread over a series of staged works.
