DigitalGriffin This will make flag type switches, and dawrf signals confusing. Red is Reverse/Thrown, while Green is normal/Closed.I guess you cant use color type semaphors for Wyes

Some railroads physically designated the points in the field:

I have some 3" tall N and R cast iron letters that came off an abandoned New York Central turnout.
I still despise the nomenclature that Digitrax likes to use 'thrown or closed' for customizing their products. To me it is quite arbritary. On my layout I use normal/reverse and have never had any problems with orientation.
Good Luck, Ed
DigitalGriffinWith normal switches, the straight route is closed. Thrown is the diverging route. With Wye turnouts which direction is closed?
None of the above.
Railroads don't use those terms.
Switches are normal or reverse. Typically normal is the straight route and reverse is the diverging route.
With an equilateral switch (wye) they will designate one route or the other as normal. Depends on where it is used. For example if it's a high speed switch at the end of two main tracks, typically "normal" will be for whatever hand running is on the two main tracks. If it's right hand running then they may have "normal" as single track to the right main track. Otherwise they will have normal be the most used or through route. If the main track is on the ledt route, then left is normal. If the main track is on the right route, then right is normal.

gregc ATLANTIC CENTRAL Whichever route the railroad decides. CTC panels identify the turnout positions as N and R, presumably normal and reversed.

Yes, "Normal" is the primary route and the position the turnout should be returned to after taking the "Reversed" route.
But Normal and Reversed has nothing to do with the geometry, the "normal" position can be the "curved" route.

ATLANTIC CENTRAL Whichever route the railroad decides. Actually, same is true of any turnout. Railroads don't care about the geometry, it is route priority that decides. Same with curved turnouts. Now, we know that when railroads need the curved route thru a turnout to be high speed, they have lots of technolgy for that, closing frogs, very large turnout size, special guardrails, etc. Do they prefer the primary route to be straight? Yes, but just like our model layouts, that is not always practical or possible. Sheldon

With normal switches, the straight route is closed. Thrown is the diverging route.
With Wye turnouts which direction is closed?
