I think we could add some more features to the trains like… we could add so you can choose what doors to open on some trains like the electro star trains. On some routes we could make so passengers can open the door instead of all the doors opening. We could have some scenario where there is a flood that you could drive past or overhead wires down. And one more thing you could do is make the black button on each end of the carriage that closes all the doors on that carriage.
