I think the side windows of cabs should have an option to stick your head out the window to add more realism so you can check the platforms or anything else
Due to how railtour operators and heritage railways advise you not to stick your head out the window of a coach due to the chance of decapitation whilst the train is in motion, It's highly unlikley that we will see this anytime soon.
Most of my rail journeys as a kid in the UK circa mid-90s was done with my head out of the window on slam door stock, I'm still here.
Yeah but back then, Health and Saftey on the railway wasn't as strict as far as I know.. Today's world is somewhat powered on H&S. Back in either 2018 or 2019, I was told off for sticking my head of the door window of a MK1 coach whilst on a railtour
