Like most of Iconographix books, this one is basically a series of photos with captions. The photos are excellent and reproduced well. Unfortunately, the captions need some copy editing. Several cars were misidentified, such as a hopper identified as a gondola, a covered hopper called a box car and a yellow and green NWX reefer described as yellow and brown. Also, note that the pronoun for a named railroad is its, NOT their! For example, "The North Western Refrigerator Line Co. painted its cars yellow and green", NOT "painted their cars ....".
Overall a good reference book for model railroaders seeking accuracy and rail fans. Dave R.
