If you are interested in those branches specifically, there is quite a bit of info (and maps) on the South Branch in a book called "The History and Legends of Rogues Hollow". You can read it online http://www.forgottenoh.com/Rogue/pages.html
There is an article in a past issue of the Erie Lackawanna Historical Society's magazine.I'll get the author on board this forum, he loves to talk local Erie history.
If you are interested in Wadsworth itself there are history books available.
To find out where industrial sidings were, and who they served, get the Conrail Youngstown Division 1984 CTS Charts from http://www.multimodalways.org/archives/ ... 20ZTS.html
These charts do not show the mainline trackage arrangements from the Erie/EL days, but it does show what industrial sidings existed. Even though some were never served in the Conrail days.
Since you're into exploring the mainline with rails-to-trails, there's another one from western Kent to Tallmadge, and a new one between Rittman and Creston. They hope to extend that one to West Salem someday.And the Cleveland branch between Mantua and Garrettsville is a trail now. I need to get out from behind the keyboard and make use of them more often!!!
