Laurel & Tullahoma Western Other Articulated Locomotives

Class 64 (Locobase 4071)

See also http://loggingmallets.railfan.net and Record of Recent Construction #67 (Baldwin Locomotive Works, 1910), p. 15. Works number was 34876 in June 1910.

This was the behemoth among Baldwin Atlantic Mallets, but 64 did not last long in service. When L&TW (or EG & co) went bankrupt in 1914, she was returned to Baldwin and scrapped, although BLW retained her boiler to generate steam.
