Sperry Car

I am very new to this forum and to train culture. I am doing research for my dissertation, which is in English literature, and am wondering if anyone can point me to books and/or information on the Sperry Car, its history, especially in the time following WWI. Any help would be appreciated. Thanks, brian

Google Sperry Rail Service. They should have a web site…Located in Danbiury, CT. Used to have motor cars…converted Brills, etc. but never Budd…now mostly done with trucks. NS is using one on the Southern Tier Line working west from Bingahmton Wed 1/20, Johnson City 1/21, Owego 1/22. It looks like an 18 or 20 foot box on a F350 or something similar.
