Tampa Northern 4-6-0 "Ten-Wheeler" Type Locomotives

Class 100 / 690 (Locobase 4997)

Data from 1929 SAL locomotive diagrams published on http://www.dnaco.net/~gelwood/other/sal--steambk.html . Works numbers were 31965-31966, 32007 in October 1907.

Middleweight Ten-wheelers taken into the Seaboard Air Line when the TN was absorbed. They lasted only until 1930, most likely because they were too small for more modern passenger equipment.
