I moved to the suburbs on the Chicago to Aurora CB&Q in the early 1950s.My house was facing those tracks. I remember that more than once or twice that Steam Engines pulled those new Stainless Steel High Level Commuter Coaches along with a grey/silver painted baggage generator car and perhaps one or two heavy weight green coaches with maybe a grey roof and I believe a yellow stripe the length of those coaches. I am hoping you would have a photo or two of those commuter runs with steam pulling those trains. I have found a couple of pictures but those are of special rail fan trips in much later years. Thanks for your time. ejm.hhm@juno.com
