What is a 4F?


Well, put simply, a “4F” is an 0-6-0 goods steam locomotive which has its origins in the range of smaller 0-6-0 designs initiated by the Midland Railway company in the late 19th Century.

“4F” is the power classification assigned to the loco.  “4” indicates a loco of medium power (in the range 0 – 9), and “F” stands for “Freight”.  (Even though the railways commonly refer to “freight” as “goods”)
