It would be great for immersion especially when using steam trains to have occasional onlooking members of the public waving near the track, especially families, thoughts?
Plenty of things like this would make the game more realistic. For example, people walking on the streets not just cars. Would be nice if the level crossings actually worked too instead of being down all the time. GTA V does this well, and you know when a train is coming. One of the things I like about isle of wight is people using the footbridge, would be nice to get people using the footbridge at Newhaven harbour etc. But I agree with your point, lineside people would be fantastic.
