There are pictures of the TA&W's Alco S-1 at www.angelfire.com/oh5/toledorailfan. scroll to the bottom of the page. A picture of their last steam loco (a 2-8-0) can be found at a web site that lists all active & static display locos in the US. Unfortunately I don't know the exact address but I'm sure you can find it by running a search for "steam locomotives". Its on display in front of the transportation center in Huntington or Charleston, WV "disgusied" as a B&O unit!
Just running a search for Toledo, Angola & Western Railway should turn up a lot of pictures. Also try the UT library site.
