Sentinel powered steam railcars enjoyed some success on the standard gauge in the UK. However, other than 4 cars on the Jersey Railway, the not inconsiderable number of narrow-gauge cars built were all exported to a remarkable number of countries and, in a few cases, had very long lives. Included in this book are basic technical details of the power units and the railcars as they developed, and their service history around the world. 82 pages, very well illustrated with B&W photos and drawings.
