Sometime in the 1950s, Railroad Magazine ran a photo of The Dude, a race-season special that ran from North Station to Saratoga on an all-B&M route. Just west of the Hudson River bridge, the special would use the Saratoga & Schuylerville Branch, sold post-WW II to the Pinslys and scrapped, ironically enough, in the 1950s.
If you use your search engine of choice, you should get a good number of hits for the Saratoga & Schuylerville. You may even get referred back to this site, because I posted somewhat the same info earlier, but given my just-caffeinated ADDness, I had neither the patience nor focus to go hunting.
