 As part of its 2009 franchise agreement, Metro Trains Melbourne was required to modify the 3+2 seating layout in all original X'Trapolis 100s to have 2+2 seating, providing efficiency in passenger flow and more standing room.Later orders of X'Trapolis 100s were delivered with this modified layout.Passengers on the Lilydale/Belgrave Line came to refer to trains made up of these cars as the 'Kosky Express' in reference to the late Lynne Kosky MLA who had been accused, as Transport Minister, of indifference to the needs of the eastern suburb's populace in pursuing policies which resulted in a reduction in the number of seats available on the 40-km trip into Melbourne by train.
