are fully accessible, however, there are some stations that haven't been upgraded to meet these guidelines. These stations do feature ramps, however, they have a gradient greater than 1 in 14. Stations that are fully accessible feature ramps that have a gradient less than 1 in 14, have at-grade paths, or feature lifts. These stations typically also feature tactile boarding indicators, independent boarding ramps, wheelchair accessible myki barriers, hearing loops, and widened paths. Projects improving station accessibility have included the Level Crossing Removal Project, which involves station rebuilds and upgrades, individual station upgrade projects, and associated Metro Tunnel works. These works have made significant strides in improving network accessibility, with more than 60% of Pakenham line stations classed as fully accessible. This number is expected to grow within the coming years, as a network restructure associated with the opening of the Metro Tunnel is completed and the completion of level crossing removal works on the corridor by 2025. Signalling Since the mid to late 20th century, the Pakenham line has used a fixed block three position signalling system designed for lower frequencies and less services. However, the ageing system had undermined reliability due to the presence of system faults and limited frequencies, requiring the Pakenham, Cranbourne, and Sunbury lines to upgrade their signalling system. Since 2021, high-capacity signalling (HCS) has been rolling out on the Pakenham, Cranbourne, and Sunbury lines, allowing trains to safely run closer together and run more frequently. The new system is being delivered by CPB Contractors and Bombardier Transportation under the Rail Systems Alliance. These works valued at $1 billion includes the roll-out of of HCS and communications systems on the aforementioned lines, allowing an increase in reliability and frequency. The line will be equipped with Bombardier’s CityFlo 650 communications-based train control system, which will enable operation at 2–3 minute headways. The upgrading works were completed in phases from 2021. With the upgraded signalling system, trains are now able to run closer to each other. The new system was tested on the Mernda line and a section of the Cranbourne line before being fully implemented on the lines. In March 2022, the Pakenham line underwent further testing of high-tech signalling equipment, to ensure the new trains and signalling system can safely run alongside older-generation trains—including freight and V/Line trains—and the existing signalling system.
