I just found out that the trains in TU are maglev trains lol. It’s all piecing together. I saw a sign saying ‘maglev station’ or something and I didn’t take much notice. I was watching a video today about one which popped in my recommended and thought “Damn, that looks like a train in TU!” and remembered the sign. Also the other day I realized the train didn’t touch the track in resort and thought it was just meant to be like that and I wasn’t meant to see it.
Also the model of the train in game looks amazing!
