Boston & Maine class G-11a 0-6-0 No. 410, built in 1911 by the American Locomotive Company's Manchester, New Hampshire, works, is displayed today in Lowell, Massachusetts. These switch engines had 19x26-inch cylinders, 200 p.s.i. of boiler pressure, and 52-inch drivers. They weighed 147,700 pounds and exerted a tractive force of 30,685 pounds. Walter Weart took this digital image in July 2006. Mr. Weart, noted for his work as a Transport Writer, was my fellow employee of Rand McNally & Company in Skokie, Illinois, during part of the time I worked there (1981-2001).
