No Smoking = lighting up?
Tunnel = scope
Just thinking out loud, but essential telling cohorts that you want to squelch to watch your back.
Spitballing
Train run in linear direction, no deviation, no shelf choice, at the direction of conductor. You are not allowed to question the direction, you are not allowed to even communicate with the conductor. When they call you listen not the other way around. My quess is they do this through the burner phones. they are handed out with nobody knowing the number and receive calls from anonymous numbers. This has now been compromised
