Shameless plug: Anyone with a serious interest in the Vans should get "Invisible Giants: The Empires of Cleveland's Van Sweringen Brothers," by Herbert H. Harwood, Jr. (Indiana Univ. Press, 2003). It's still in print, as far as I know, and you can get it through Amazon.com and other such outlets. As a warning, there's a lot of mind-numbing financial stuff in it -- unavoidable, since that's what the Vans were all about -- but enough on railroads, rapid transit, and Cleveland real estate projects to keep you awake.
I figured it was you, esp when you spoke of your Chessie background/connection plus your extreme knowledge of the topic. Some people prefer internet anonymity, so I remained silent... I'm ashamed to say I only thumbed through your book a few Xmas' ago at a Cleveland bookstore and made a promise that I'd someday buy it because it was by far the most comprehensive I've ever seen on the subject ... Definitely an Amazon bet. The Vans were such a mystery and, as the book, swept to the side of history, personally (perhaps modern leaders keep their distance because they cringe at the Vans' harsh anti-black/anti-Jewish housing covenants in Shaker.)
I think RTA and the County (via ODOT) has pretty much wiped out most evidence of the Vans' old East Cleveland line stations and station-stairwell openings with their bridge rebuilding and rehabbing. A few may exist in East Cleveland though, I’m not sure, as I’ve relocated from Cleveland also (I still visit frequently, though)… It appears the Vans only got a concrete start on the 4-mile East Cleveland branch but only Rapid reservations along the NKP west line. Years ago I read a 1920s Parsons Brinckerhoff plan, obviously prepared for the Vans, that called for the NKP east and west lines to be built, 1st, from the Collinwood/Euclid Border thru Lakewood on the west... I'm guessing since the Vans cos. owned NKP it was easier to build along NKP's east-west line than next to other rail lines entering the city.
Do you know why NKP stopped their extensive grade separation program at W. 110th street while proceeding much further on the east? (scold me if your book holds the answer... shame on me)
