5 Locomotives and Multiple Units that I'd like to see in Train Sim World 4

I've noticed that most Train Sim World routes are very safe, as it were, when it comes to the route choice and the types of services on offer. For instance, there's quite a few German routes that follow a boring formula; short to medium-length electrified lines with a generic mix of passenger and freight services. It's not much better on the British and American routes, and don't even get me started on the shocking amount of countries (e.g. Australia, New Zealand and Japan) that still haven't got a route of their own in TSW.

What I mean is, none of these routes have any truly unique operating practices or motive power, and I think that is slowly spoiling the game. This video is focused on five unique motive power types that I want to see as DLC packages in Train Sim World 4:
EMD F40PH (the original Amtrak variant)
Melbourne's Comeng EMU
Southern Pacific AC-12 or 'Cab Forward'
Class 91 electric locomotive
Wellington's FP / FT 'Matangi' class EMU

Although I forgot to bring it up in the video, I would love to see mountain railways with a rack-and-pinion system in TSW. Examples include SkiTube in Australia and Line C of the Lyon Metro in France, even though they're both electrified.
