I would love to see the Melbourne Metro network in train Sim. It is a broad gauge, 1500V DC Network with a selection of 17 lines to choose from. There are 3 types of passenger trains as well as the occasional freight service. The 3 passenger trains are: - Alstom X-Trapolis 100 https://en.wikipedia.org/wiki/X'Trapolis_100 - Siemens Nexas https://en.wikipedia.org/wiki/Siemens_Nexas - Commonwealth Engineering "Comeng" https://en.wikipedia.org/wiki/Comeng_(train) There is also a new train to be introduced in mid 2019 which has been named "High Capacity Metro" https://en.wikipedia.org/wiki/High_Capacity_Metro_Trains The Freight services tend to be operated by NR Class Desiel Locos https://en.wikipedia.org/wiki/National_Rail_NR_class Seeing this in Train Sim would be a great way for DTG to introduce new countries to the game.
