For instance, your PV car develops a problem serious enough to require immediate assistance while actively being hauled behind Superliner equipment.
Maybe it's an electrical fire. Or a heart attack. Or a botched undercover police raid or assassination attempt while passing through Dallas.
Can you just pick up a radio?
Is there an active intercom connection?
A flag you're supposed to wave?
A whistle you're supposed to blow?
A hammer to pound against the next car?
A spotlight with signal filter?
Smoke signals out of the stovepipe?
What is the protocol? Inquiring minds want to know!
