I play world of tanks a lot, and I've noticed that in most maps there is at least one train. The game itself has nothing to do with trains, they are merely a decoration, but looks like so much attention was put into modelling trains and rail. Sometimes I ignore the game and drive around the trains to look at them. I was wondering are there other games like this, that have nothing to do with trains, but have trains in them, just for fun, and trains are rally nicely modeled or maybe even interactive in some way.
Red Dead Redemption 2 barely has a focus on them, but they're nicely done and you can even drive them!
Metro Exodus has a train as an integral part of the game: https://metrovideogame.fandom.com/wiki/Aurora
Assassin's Creed Syndicate contains steam trains. In fact, one of the trains is the assassins hideout.
Splinter Cell: Pandora Tomorrow had one of my favourite missions in the game where you move on top of, though, around and under a moving train. James Bond 007: Everything Or Nothing had a mission where Bond must fight his way along a Train, finishing in a fight with Jaws. Not only that, but the mission before has you having to chase the train and board it before you run out of road.
