I grew up in Albany and left for Mass. at the age of 11, so I have foggy memories of Troy. I do remember the giant factory buildings and glaring lights. My mom also liked to visit a fabric outlet there, and would buy cloth to sew out Easter outfits. Not much help, eh? But it could be a scene in your book! I do that with my writing: insert little vignette's from my own and others' lives into my story line. It helps me...I don't know about your style.
Kurt Vonnegut Jr., wrote a novel based in Troy, (Player Piano), involving corporate greed and corruption. Though it's fiction it might be useful. He was also employed at G.E.,--though I'm not sure if it was the plant in Schenectady) after returning from the war. he often refers to Troy in his other works as "Ilium" (the Greek name for Troy).
This site deals with the housing conditions of Troy from the 1920's on:

Doing a search, I found one interesting sight about factories in Troy during the 1950's:

Just type in "Troy, NY, factories, 1950's" and you'll get more info than you can use, I think! Switch it around to include, words like "education" and so on.
Good luck!
