I use the keyboard to control my locos, don't even have the controller showing on the screen. I like my screen to be completely clear when operating trains. Would the direction orientation of the cars I'm pulling have any bearing on this at all?
The direction orientation of the cars you are pulling has no bearing on your operating problem. I often have tail-ended locos reversed-facing and it has no effect, because it is the lead loco that is actually in control.
I do prefer to set individual routes for each train and I do this via 'Central Portal Control' - In addition, I usually have 'entry' & 'exit' Portals set up at all ends of my routes which launch new and different trains every 5, 10, 20 minutes apart. For it to run smoothly and without any major stoppages, it is important for my routes to be signalled properly.
I also like to have a completely clear screen in order to take screenshots when I like. I still use a mouse but if you press the F6 key, it toggles your task-bars and other controls on and off.
So, once I have my route all 'programmed-up' I can sit back and enjoy the ride and view. And, if I want to change trains or check the progress of new trains entering the route via a portal, I just toggle F6 - it's easy.
I also get more satisfaction when I can see 20 trains all running to schedule.
Before I retired, I was a manager of an insurance company, so I like to delegate and give orders. Trainz gives me the opportunity to still do that.
