Sandringham Metro Line
Advanced Train Control Capacity Analysis

Melbourne, VIC

As the name implies, Public Transport Victoria (PTV) is responsible for the oversight of all public transportation services in the State of Victoria. This includes an extensive network of trams, trains, buses and coaches. The tram system is the largest in the world, and the metropolitan train network is among the largest in Australia.

PTV selected our team to develop a comprehensive operations and electrical simulation model of the Melbourne network. Parent Company LTK Engineering Services proprietary TrainOps® software was used for this assignment. TrainOps® has powerful train performance, rail infrastructure, electrification and train control systems modelling capability.

As part of the assignment, we were tasked with quantifying the capacity benefits of advanced train control systems on one of PTV’s 16 suburban lines, the Sandringham Line.

In the first portion of the analysis, NDYLTK applied TrainOps to quantify the capacity (under wayside signalling and under CBTC) of the line, ignoring the terminal constraints at Sandringham and crossing and terminal capacity constraints at Flinders Street, a major downtown station.

In the second part of the analysis, actual scheduled Sandringham line operations were modeled under the current wayside signalling system and under CBTC.

TrainOps was used to quantify the time required to restore service to scheduled operation after an unplanned extended dwell for both train control systems. Finally, TrainOps® produced unimpeded (off-peak) travel times under both wayside signaling and CBTC with the latter providing enforcement of all civil (“timetable”) speed restrictions.
