Seems like a pretty good system and I guess you can understand why
running a service without it would be difficult.

Out of curiosity, how did the service operate before the use
of these radios? Two men in the cab, or a less thorough
approach to safety?

Guards.

Duh! Of course. Thanks for politely answering such a dumb
