they have a Bve Multiplayer that u can download at bve station.com
If you read
"With BVEStation Multiplayer Live you have the ability to interact with fellow members of BVEStation in operating one of the largest subway systems in the world, in BVE! In collaboration with the New York City Transit Authority Routes for BVE, operators will be connected to the Teamspeak server, while they operate the BVE routes, taking orders from the Train Dispatchers who are also connected to the teamspeak server. All is done through radio tranmission (voice) through the Teamspeak server, giving players unparalleled realism in playing BVE and simulating a actual radio transmission between dispatchers and train operators. You have to try this out yourself to experience the full fun of BVEStation Mutliplayer Live!"
You are talking to someone using your microphone (online) but you are not connecting to them in any other way. You recieve an duty from the dispatcher on TeamSpeak.
Its not multiplayer in the way i think you were hoping it was :roll:
