NYO&W Northfield Zig Zag

Anybody have a map, or otherwise know of the routing of the New York & Oswego's "Zig Zag"? It was a switchback(s) which took the railroad line over the hill that the Northfield Tunnel later penetrated on the level. Interestingly, the telegraph code for the Northfield station was "ZA" to the dying day of the NYO&W even though they built the tunnel in 1890.

Did you ever find anything on the zigzag at the O&W Northfield - I'm looking for the same thing for a presentation

I think the switchback route is to the right of the push pin.

I have the maps at home. I'll be back later to find the rest of the route.

A few quick estimations:

#2 and #5 are really to the left of where they are.

There are two diffrent Bird's Eye maps here.

Looking at the maps I copied from an O&W book (I'm not sure which one), I added the tail track on the Merrickville side.

A northbound train would pull into the depot at "North Walton." It would back up into the tail track of the only switchback on the North Walton Side.

It would go upgrade through the location of Push Pin #6, Push Pin #5 and Push Pin #4.

It would stop at the end of the first switchback on the Merrickville side, Push Pin #7.

The train would back up to the second switchback on the Merrickville side around Push Pin #3.

The train would pull forward and pass the Merrickville station.

Can everyone see this?

Yes, it seems blazingly obvious on the Bing Maps oblique aerial photographs. Definitely have to get down there some time! I've added the routing to OpenStreetMap: http://osm.org/

^Good job. Thanks!
