Carter B-This is quite an undertaking! Here are a few I'm aware of from the area where I grew up:
Chautauqua Traction (Chautauqua County, NY):
Station at Ashville, NY still stands, was used as a hobby shop in the last 20 years. (Scroll down to photos)
Here's a more recent photo:
Entrance building to Chautauqua Institution also served as a trolley station on this line:
Actually, there are a number of existing stations for both the JW&NW and Chautauqua Traction that I'd forgotten about. (I haven't lived in the area in over 30 years but still go back yearly to visit my father.) From Charles Woolover's "Existing stations website, here's a listing for both interurban and steam road stations in Chautauqua County:
Jamestown, Westfield and Northwestern (Chautauqua County, NY):
Station in Jamestown still stands, now used as a business.
Midway Park, Maple Springs, NY is one of the few remaining "trolley parks" in the US, originally built by the JW&NW. More on Midway Park: http://www.nysparks.com/parks/167/details.aspx
Warren (PA) & Jamestown (NY) Railway (Warren County, PA, Chautauqua County, NY):
Power house/shop building (Brick structure) still stands along Pennsylvania Route 6 in Stoneham, PA used as a business.

We had a long running discussion on trolley parks in the forum a couple of years ago (That I believe you participated in.) including a list of those that still remain in business.
