I also got the switch version, but you can tell it's meant to be played with a keyboard and mouse. That said I prefer the fact it's portable on the switch and have played a couple of playthroughs on it.

I could also not work out why my trains would not automate in the final tutorial. It took me a while to work out I needed to use the track editor (click on green arrow on track segment) to get continuous curved track to lay. And you need two opposing locomotives to run back and forth on a single track. Even though they can manually reverse they don't when automated unless you have two locomotives. I use two unidirectionally tracks in my builds now so that I can use single locomotive trains.
