The June 2010 issue of TRAINS (p55) has an advertisement from the Colorado RR Museum for the Colorado Rail Annual #30. "...An illustrated encyclopedia of 10-drivered steam engines in the United States, examined in detail, including the origins and subsequent changes in design." $59.95 303-279-4591 800-365-6263 I don't know what the Frisco content might be, but no doubt the Bolsheviks will receive some coverage. I have ordered a copy.
