Approach Restricting

[NW Mailing List]

Earlier, rules regarding signal indications related the speed in the name,
at least in that "diverging" was earlier termed "medium."

I'm not aware of where "Approach Restricting" would have been used on the
former N&W, but I recall seeing "Approach" displayed in advance of a
"Restricting" indication just as in advance of a "Stop and Proceed."

The one "Diverging Aproach Diverging" I've seen was Roanoke EB at 2nd Ave
where the signal and crossover spacing gets tight.
