Barry Railway Class F were steam saddle tank engines of the Barry Railway in South Wales. They were designed by J. H. Hosgood and built by a number of British companies.
The purpose of this locomotive was to carry out heavy shunting duties at Barry Docks. They were in effect a saddle tank version of the Class A, a locomotive which had carried out shunting duties at the docks up to this point. 28 examples of the Class F were manufactured, making it the second largest locomotive class used on the Barry Railway, outnumbered only by the B1 Class. They were fitted with a reversing lever, far quicker for changing direction during shunting duties than the . They were all shedded at Barry, and they occasionally worked goods and coal traffic on the main line in addition to their main shunting duties.
The locomotives passed to the Great Western Railway in 1922, but were withdrawn between 1926 and 1936. However, since they were still in workable condition many were sold privately, the details of which are listed below.
