| Like its sister #4000 in this album, this unusual "cobra hooded" Coffin feedwater heater equipped locomotive was an unusual sight. Built by Lima in 1928, this class T1a Berkshire-type locomotive had 63" drivers, generated an impressive 240 psi of boiler pressure for its 28"30" cylinders, had an engine wieght of 406,900 lb, and could produce a respectable tractive effort of 76,160 lb. With all of that however, Boston & Maine had problems with the class from the very beginning - mostly due to the trailing 4 wheel turck which caused twisting motion on curves that produced leakages and often resulted in derailing when backing. B&M sold the class to Southern Paciifc and Santa Fe during WWII. No photographer listed for this photo. The day in 1938 is an approximation. |
