I think that Melbourne/Victoria would be an amazing addition to the game. By the time TSW6 is out, the Metro Tunnel would be open, so my suggestions for routes would be: Route 1: Metro Tunnel (Pakenham/Sunbury Lines) With the HCMT, make it so players run the entire metro tunnel route. The metro tunnel is auto-driven, so it would be cool to see that part too. Route 2: Frankston Line When the Metro Tunnel opens, the Frankston Line will be sent into the city loop, so it would be cool to use the Frankston Line with the Xtrapolis 100, Comeng and Siemens Nexas on the Frankston line in the city loop. Route 3: Through-running Group Again, Metro Tunnel. This will mean the Weribbee, Williamstown and Sandringham Lines can either run seperately or connected as options with the same train selection as above. Possible Alternative to Route 2: Instead of running the Frankston Line, the City Loop can be used on the Mernda or Hurstbridge lines. It would also be cool to maybe have V/Line trains in the expansion too but would be a stretch. I would love to hear the community's opinions on this!
