heres a suggestion for the developer m-iden you should include a feature that when you arrive at a station an announcement comes over the speaker for train your operating. and you see AIS walking on the platform towards your train and if you have a certain amount of points you can spend them on crew for your train such as: a platform porter, tickets master, station gaurd and operator, train signaler and gaurdsmen which blows a whistle to let people know their departing. maybe even a viewable cab where you can see a train driver in the seat or if its for the steam locomotive you can see a firemen or a stroker puting in coal.security gaurds on each platform and maybe in your train. thats an idea you should add to the game in the next update.
none of these actually improve the game experience and distract from improving the game with new missions, trains, maps and mechanics. Not to mention this is an indie game, not a triple-a game which has resources to spend on having a fucking porter. if you want a game which could have those sorts of features, play a tycoon game or a game like Train Sim World
