This is a peculiar booklet. The ten interior pages each contain an interior photo of a Rio Grande passenger train, accompanied by an average of just 15 words per photo. While there is a system map on the back cover, none of the interior pages mention specific trains, routes, destinations, or the scenery visible from Rio Grande trains.
The cover photo showing a 1929 locomotive pulling a passenger train appears to have been “photoshopped” as the train would otherwise be emerging from the solid wall of a canyon. While the booklet is undated, it must be from the late 1930s, as the map on the back cover shows the Dotsero Cutoff (opened in 1934) and the Uintah Railway (closed in 1939).
