I am aware that a lot of people want multiplayer, but also aware that it could lead to track fouling. 1. My suggestion for multiplayer, is to limit the number of players to a server in that, only 4-5 people can drive at a time, so as not to foul up the tracks, but allow others to play as passengers, railfans, conductors, or yardmasters. More so, I would really love to have the ability for someone to play the conductor role... Someone who can help switch points, assist with coupling, etc. 2. It would also be really cool, if grade crossing gates worked as they do in the real world, rather than be perpetually lowered. I'd like to see the gates actually coming down, as the train trips the signal. In addition to that, it would also be really cool if AI trains were to blow the horn, when approaching grade crossings, as in real life. 3. Even if AI, railworks would be an awesome touch... Even if just on an unused siding as part of scenery. Ie; rail work trains, ballasters, etc. Which, would also be a really cool DLC. Make it so that you have to go out to repair tracks, clear snow drifts, etc. 4. I'm sure it's been brought up before, but... Radio comms! Could be just atmospheric, but would be cool to hear chatter on the radio, or even be able to verbally request signal passes with a headset mic/make announcements on commuter trains. The in game radios have functional buttons, but with no purpose. Would be even better if multiplayer was added, and HAD to use the radio to communicate between crewmen/ yardmasters.
