BN C424 4241 leads three SD45's on what I would guess is WP track in Northern California. No Information on slide as far as location or photographer. Slide has been in my collection for years.
An Ex Q GP30 leads a NP F and a BN unit eastbound near Wishram in this photo from my collection. The name of the photographer is quite faded but appears to be Tom Brown.
BN had quite a fleet of EMD covered wagons and they lasted into the early 80's. Here is an A-B-B-A set on train 123. This is a slide I traded for years ago, no photographer information on slide.
Milwaukee Road 101A leads a F7B and E9 along with what I would assume is the Afternoon Hiawatha at New Lisbon. Photo has been in my collection, no photographer listed on slide.
A nearly new GP30 heads up a few GP20's on this Q train shot at Cicero in 1963. Photo from my collection and was traded for. Photographer appears to be R. Olmsted but is quite faded.
