The album, with 189 images, is a collection of Northern Pacific freight car and caboose photos mostly taken in the 1970s in Minnesota, Wisconsin, North Dakota, Montana and Washington. The box cars range from wood-sided to "waffle-side" in a variety of paint schemes, covered hoppers include the "Conditionaire" cars, there are numerous GS-type gondolas and the cabooses are of both the wood and steel varieties.
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.
