In late 1935 the NS fitted streamlined cladding to 3700 class 4-6-0 No 3804 which then re-entered service in January 1936. The purpose was to reduce coal consumption by reducing the wind resistance which after extensive trials proved to be the case. So a further five of these engines, Nos 3800-3803 and 3805, were fitted with streamlined casing in 1937-38. The decision to remove the streamlining from all the engines was taken due to wartime conditions in October 1942. The 3700 series was first built by Beyer, Peacock & Co., Manchester in 1910 but the five engines streamlined came from Henschel & Sohn, Kassel in 1920. Photo by the late Colling Turner.
