A More Favorable Signal

For the past couple of days, we have been delayed a few minutes on the NJTransit train.

Usually the conductor announces over the P.A.:

Ladies and gentlemen, we're currently being held at a stop signal, once we receive a more favorable signal, we'll be on our way.

This gave me pause.

"A more favorable signal."

Ok, fair enough. And eloquent, I might add.

But, here's where I'm confused: What are the favorable choices, besides Green?

Are there more options? Is there a new system of lights, sounds, pictures and phrases to help us get over the Passaic?

One can only guess...so I did.

Favorable signals:

• Green
• Yellow
• Taupe
• Hello gorgeous!
• Nice weather we're having...
• Did you lose weight?
• No nukes
• ::big thumbs up::
• ::bucket of wings::
• Get a move on, tubs.
  
• Pass the dutchie on the left hand side.
  
• ::theme from Bonanza::
• Can-can girls
• Picture of cartoon train wearing running shoes
• ::whip crackle::
• Zepplin laser light show
• Guiliani
