Would be quite good if there were more passengers, I think it would add to the realism and immersion, not for every station obviously, just the main ones and more built up ones. Could make some passengers walk around on the platform too? Cause at the moment it's a bit weird seeing stations like Paddington and Victoria just... Empty lol. It makes sense having less people at smaller stops, but not main stations. Although I can understand that adding more passengers could effect the performance of the game, just an idea I suppose. Also, to go with other peoples suggestions of working departure boards, maybe the implementation of a voice announcer like Anne that is heard at all main stations? Would add even more to realism and immersion. Again, just an idea.
