Amazing what is out there:
Decision by authorities that the CT will have to cross the LSMS on the Portage St bridge:

1921 Abandonment Decision of CT between Barcelona and the LSMS: at the bottom of page 107 it says that CT ran on the highway between those points (Portage St).

OK, now for my idea on the south end of town. I think we all agree that coming in from Mayville, near Westfield the JWNW followed the S-curve on the topo in the first post in this thread, that it crossed Portage St just south of what is now E Campbell St, and then ran on the west side of Portage St. If you look in street mode on Google Maps, near the bend in Campbell St, you can still see what I think was the south abutment that carried the JWNW over E Campbell St. I somehow can't figure out how to make a direct link to the view.
Now this 1906 official report on RR crossings in New York:
http://books.google.com/books?id=FdYpAA ... ld&f=false" onclick="window.open(this.href);return false; and click on the page 172 link. It says that that CT may cross the Jamestown, Chatauaqua and Lake Erie Steam RR (what later became JWNW) "in an existing undercrossing near Factory St" Looking at old Sanborn maps, Factory St was very near or probably the same as the modern E. Campbell St (actually it continued across the Creek and joined what is now West Campbell St). So we can assume that CT went under JWNW at what is now E. Campbell St at the abutment.
Note on maps that there is an "Old Portage Rd" where Gale St joins Portage Rd. The straight section of modern Portage Rd which is a cutoff to Old Portage Rd is new, confirmed by old maps
http://historical.mytopo.com/getImage.a ... g&state=NY" onclick="window.open(this.href);return false;. Furthermore, the old Portage Rd had an exceeding steep drop and rise (see the old and new topos) in a ravine. The grade on Gale St is much less initially than that on Old Portage Rd.
So coming from the south, I think
a. CT came from Mayville on Portage Rd
b. At Gale St, CT got off Portage Rd (to avoid the steep grade at old Portage Rd) and then followed the dotted line on the topo map in the first post.
c. Then I do NOT think that the CT and JWNW RoW's merged as shown on the topo map near Campbell St. Rather, I think the CT joined E. Campbell St just west of where the dotted line junction is shown, and then ran UNDER the JWNW where it crossed E. Campbell St.
d. The CT then ran east up E. Campbell St to Portage St and continued north, all the way through Westfield (and to Barcelona when it was extended).
I don't know how to incorporate that into Open Street Maps, though. Comments and suggestions?
