To give you all a idea what I trying to achieve and you can est it as well.
When you purchase a New South Wales EMU it usually 4 car sets .. so you need to purchase it in 3 sections .. power cars, middle car, and next middle car. So EMUs are 6 and 8 car sets. 8 car set will require you to buy it in 6 parts.
The new EMU D-Sets that will start operating between Sydney and Newcastle this year. They are running around the network now training crews.
For now I showing the start date in game as 31st May 2021. They are in 4 and 6 car lengths. They can operate attached to each other in any combination. But you can not reduce or add any middle cars.

So give them a try and see if you like all the EMUs to be like this.
At moment there are 4 sets of V_Set EMUs in the game .. this new coding will allow me to reduce these to just 1 and still have the new colour schemes when those years arrive. But if I removed those 4 sets and replaced with just 1 set it will crash you game.
So I seriously thinking I start a new "
AuzTrainsNSW" and call it "
AuzTrainsNSW_revised_Set" .. and it will have the EMUs, DMUs in their correct combinations for realism.
Give the D-Sets a try and let my crew and I know what you think. Cheers
