line. The journey from Holmesglen to the terminus involves some of the steepest grades in Melbourne (1 in 30). However, sections of the line have been elevated or lowered into a cutting to eliminate level crossings. Despite some removals, there are a small number of level crossings still present with no current plans to remove them. The line follows the same alignment as the Alamein, Belgrave, and Lilydale lines with the four services splitting onto different routes at Burnley. The Glen Waverley line continues on its south eastern alignment, whereas the Alamein, Belgrave, and Lilydale lines takes an eastern alignment towards their final destinations. All of the rail line goes through built-up suburbs towards its terminus in Glen Waverley. Stations The line serves 20 stations across of track. The stations are a mix of elevated, lowered, underground, and ground level designs. Underground stations are present only in the City Loop, with the majority of elevated and lowered stations being constructed as part of level crossing removals. Infrastructure Rolling stock The Glen Waverley line uses X'Trapolis 100 electric multiple unit (EMU) 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, Glen Waverley 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.
