Softcover, 48 pages, B&W photographs with captions, color covers, high-quality glossy paper.
This B&W photo book covers the many (but not all) classes of B&O switchers and Road-Switchers beginning with the 1926 class CG, an 18-ton Plymouth gasoline dinky used on the Philadelphia waterfront. Other classes covered include early EMC and EMD switchers and Road-Switchers (SWs and Geeps), early ALCO, Baldwin and Lima switchers plus Fairbanks-Morse switchers and Road-Switchers.
The B&W photographs are from the Bob's Photo collection and extensive captions by David Sweetland complete the book.
