We need toilets. That's it. Seriously what more do you expect me to say. We have had 2 games with a 3rd one on the way and there has not been a singular toilet in any of those. Going to the toilet is a vital part of your normal life so why not add them in the game. We have seen doors for the toilet on almost every train that is in the game right now, yet we've never been able to open those doors. (I just want toilets not a complete digestion system)
On the M3 and M7 LIRR and Metro-North Versions these are the odd units. Same will apply to the NJ Transit MLV I-IIIs and Arrow IIIs
If the Guard scenario gets extended access to the toilets will be essential to check for fare dodgers.
If we get a Queensland Rail route in the future, I can put some pics of station and train toilets on the thread. Also, we should be able to set the hand dryers off. Oh and we can have AI using the toilets and the urinals. That's it.
