I found this classic steam era photograph from the former Pennsylvania Railroad at My Link page Yesteryear Depot.Com, located to the right of Your computer screen at http://www.yesteryeardepot.com/

Railfan photographer Fred C. Stoes, captured Pennsylvania Railroad K 4 class 4-6-2 Pacific type steam locomotive # 1453, pulling a passenger train near Chicago's Englewood Union Station on the south side of Chicago in the year of 1948.

Yesteryear Depot.Com is a really wonderful website, and I highly recomend viewing their many fine selection of vintage railroad photographs.

Thanks.
