The presentation is like looking through a book on a computer. The CD-ROM works in PCs (WIN 2000/XP/Vista/10) and Macs and is self-starting. The images can be printed out.
The 102 images come from Color and Black-and-White photos, slides and postcards in the states of Illinois, Iowa, Minnesota, Missouri, South Dakota and Kansas. In some instances, there is the original depot and its replacement. The depots are grouped by state.
