signal use

[NW Mailing List]

Larry, et al.:

I've attached an interlocking diagram of Carrothers circa 1967 that will
likely confuse the situation even more! :). I'll need to dig around and
find out when the N&W completed the upgrades to the Sandusky District to
make it TC/CTC. I'd say sometime in the early 1970's.
