Betsy, when finished, was 24 feet overall and weighed about 12 tons. Her boiler was a curious “T” type, that is a vertical boiler with front extension (a sort of 1902 uplift model), the entrance end being topped with a jaunty little spark arrester. Just how the two sections of boiler held together bumping along on a log railroad is not explained, but the amazing thing is that it worked well and Betsy remained in service for nearly twenty years.
