trains operating in a two three-car configuration, with three doors per side on each carriage and can accommodate of up to 432 seated passengers in each six car configuration. The trains were originally built between 2002 and 2004 as well as between 2009 and 2020 with a total of 212 three-car sets constructed. The trains are shared with 7 other metropolitan train lines and have been in service since 2003. Alongside the passenger trains, Lilydale line tracks and equipment are maintained by a fleet of engineering trains. The four types of engineering trains are: the shunting train; designed for moving trains along non-electrified corridors and for transporting other maintenance locomotives, for track evaluation; designed for evaluating track and its condition, the overhead inspection train; designed for overhead wiring inspection, and the infrastructure evaluation carriage designed for general infrastructure evaluation. Most of these trains are repurposed locomotives previously used by V/Line, Metro Trains, and the Southern Shorthaul Railroad. Accessibility In compliance with the Disability Discrimination Act of 1992, all stations that are new-built or rebuilt are fully accessible and comply with these guidelines. Half of stations on the corridor 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, and individual station upgrade projects. These works have made significant strides in improving network accessibility, with more than 59% of Lilydale line stations classed as fully accessible. Future station upgrade projects will continue to increase the number of fully accessible stations overtime. Signalling The Lilydale line uses a combination of three position and automatic and track control signalling. Three position signalling was first introduced on the line in 1919, with the final section of the line converted to the new type of signalling by 1985. In addition, automatic and track control signalling is used between Mooroolbark station and the lines terminus in Lilydale.
