Wye Turnout; was: (erielack) Signal question - East Lincoln Park



This configuration is also called an equilateral turnout. Are the terms 
interchangable, or is each used in specific circumstances? I have only seen 
"equilateral" used where both diverging tracks were mainline, either single 
main splitting to double main, or 2 mainline routes.

A "wye" turnout is one that is curved on both legs in opposite
directions (as opposed to a standard turnout, which has one straight leg
and one curves; and a curved turnout, where both legs are curved but in
the same direction). Basically, picture a "Y" :)

Since neither leg is "normal" (on a standard turnout, this would be the
straight leg), normally you'd presume there would be some sort of speed
restriction regardless of which route you took. I used to wonder why EL
didn't move the track to orient the Boonton Line side as "straight", but
that wouldn't buy you much since there was a speed restriction on the
tight curve onto the Boonton Line only 1000 feet ahead.
