ok are first UK locomotive! a L&YR class 28 steam locomotive! history: The Class 28 only came into existence with the introduction of the Hughes Classification scheme in 1919. Prior to this, locomotive classes were identified by the running number of the first delivered unit. This method of designation was often confusing, particularly because the Lancashire and Yorkshire Railway (L&YR) frequently reused numbers from scrapped locomotives for new ones. In some cases, the same numbers were assigned up to four times. New number blocks were only created when the locomotive fleet needed to be expanded. The 898 Class of the Lancashire and Yorkshire Railway (L&YR) was the first British locomotive class to be equipped with a Schmidt superheater. The two prototype locomotives, numbered 898 and 899, were delivered in November 1906. These locomotives retained their round-top boilers but featured extended smokeboxes. Following successful trial operations that demonstrated coal savings up to 12 %, an additional 20 locomotives of the same type were ordered and delivered in 1909. Another batch of 20 locomotives followed in 1912. These later locomotives not only had superheaters but also incorporated Belpaire fireboxes, and were designated as 657 Class. The boiler was similar to the 816 Class tank locomotive, later designated as L&YR Class 5. The success of the superheated classes and the enhanced evaporation performance of the Belpaire fireboxes led to the conversion of 63 locomotives from 11 Class and 41 Class starting in 1911. The non-converted saturated steam locomotives of these classes were reclassified as Class 27 after 1919.[2] The locomotives briefly passed to the London and North Western Railway (LNWR) in 1922 and then to the London, Midland and Scottish Railway (LMS) in 1923. The LMS assigned them the power classification 3F. Their LMS numbers ranged from 12515 to 12619, with gaps.[8] In 1948, the surviving 35 locomotives were transferred to British Railways (BR), which renumbered them from 52515 to 52619, also with gaps.[5]
