The specification lists the projected weights as 40,000 lb on the drivers, 60,000 overall. Given the 5-ton and 6-ton increases in weight to those shown as "actual" on the sheet, Locobase suspects that the estimate was based on a narrower-gauge locomotive.
An 1885 US Treasury Report on the internal commerce of the United States described the J, T & K W in overheated tones on page 403 as "...another young colossus which has planted its feet with long strides and firm tread upon the remote parts of the state. It is the latest in setting out and the sturdiest in adventure."
Ambitious perhaps, but not all that sturdy. In the year after this pair of tanks was delivered, it consolidated the Palatka & Indian River and the Sanford & Lake Eustis. Moreover, the line did make it to Titusville, a key hub in the center of the state. By 1892, however, the J, T & KW was placed in receivership in July 1892. The line was taken over by Henry Plant's Savannah, Florida & Western and ultimately was absorbed by the Atlantic Coast LIne in 1902.
Both tanks were rebuilt as 0-4-0Ts and later sold to Cuban railroads.
