The wiki says this:
"It is also possible to persuade (70 effective skill required) the bandits to leave the train. This leads to opportunities to join either Protectorate or Free Drones, depending on what you do with the knowledge of the train's location."
I just tried this out, intending to join the free drones. I persuade the drones to leave the train, then head to the core city metro to see if the drones chick is there; she's not. I go to herve and all I can say is that I found the train. I don't think it's true that you can join the free drones if you persuade the bandits to leave. If I'm wrong, does anybody know what I'm supposed to do?
