Hello - Can anyone tell me what size frog the N&W specified for their siding turnouts, or did they vary from place to place? Thanks.

Common sense would say that they varied as to the size of the turnout AND the fact that the turnout originally belonged to whatever "Fallen Flag", not NS, put it in to begin with.
He said N&W, not NS.
Another factor might be location. An industrial siding or yard track might be fairly sharp which prototype might be 10-12 (as opposed to 4 in O scale). On mainline crossings and such they might be in 20s to maintain speed while going through.
There might be a company standards book someplace specifying what size to install in new work for each application.
Hi PRRJIM - Thanks for your helpful reply.
The online archives of the N&W historical society may be helpful (I found a drawing of a switch with #8 frog, for example), at least for finding out what is available in their collection of drawings. I suppose you can purchase copies of drawings, although I don't know for sure.

The link doesn't work.

Arthur,
When I posted, he indeed had written NS. Which is why I mentioned "Fallen Flags" as each did it their own way.
And again, the frogs would vary depending on the size of the turnout used.
I'm sorry my link didn't work properly, but now you do have a good link from RTRAINCOLLECTOR.
