Eastern Tennessee & Western NC 4-6-0 "Ten-Wheeler" Type Locomotives

Narrow-gauge Consolidation celebrated on its 80th birthday (February 1997) on the urbaneagle.com/slim/etwnc-no12bday.html website. Unfortunately, the site gives neither the boiler pressure nor the driver diameter, although the author does say the locomotive generates 19,100 lb tractive effort. The estimated BP shown in the specs is similar to other Baldwin narrow-gauge engines of this vintage.
