This was the largest single class of Ten-wheelers on the RF & P. Although they were not superheated, the 101s only started retiring in 1930. Most were gone by the end of the decade, but a couple served through World War II.
According to Drury (1993), these Ten-wheelers reflected the RF & P's need to run freights nearly as fast as passenger trains. A 62" driver would satisfy both service requirements if the operator wasn't looking for express speeds.
Ever-larger and heavier trains meant these locomotives were no longer suitable for the RF&P. A relatively new and powerful 4-6-0 could serve short lines for years and all six enjoyed second careers.. The Georgia & Florida took the 30-31 in 1916, renumbering them 201-202 in 1920. 32 went to the High Point, Thomasville & Denton in North Carolina and the Morgantown & Wheeling of West Virginia bought the 33-35 in 1923..
Although virtually identical to the 6 Richmond engines of a year earlier (Locobase 7116), these Baldwins had slightly smaller fireboxes and put 3 1/2 tons less weight on the drivers.
Like the Richmonds, these were sold in June 1916 to the Georgia & Florida, which renumbered them 203-204 in 1920. 204 was scrapped in September 1935, but 203 was sold in April 1935 to the Appalachicola Northern as their 150.
