I can’t remember if I was at the front or back of the train. I’m going to guess the end, but it’s not my final answer.
In Vancouver, the SkyTrain is fully automated so you can sit at the front or back and watch the tracks through the windshield. I would often stand at the end of the platform and, once in a while, get the end seat. Sometimes I’d take videos with my iPhone but here’s one by Sigis Travel Videos.
I’m all for self-driving and can’t wait to get one. I would rather sit as a passenger and watch the scenery than pay attention to mind-numbing traffic.
