0-4-0 'Y' Locomotives of the LNER

0-4-0 Tender Locomotives

The 0-4-0 is associated with the earliest steam locomotives, but one of a pair built as late as 1868 on the North British Railway (NBR) survived to Grouping (1923). Many of the Y9 'Scottish Pugs' also ran with wooden trucks as coal tenders but these were classed as tank engines.

0-4-0 Tank Locomotives

The 0-4-0 tank was a popular choice for light shunting duties where tight curves were involved, such as docks. Many railway companies used them, though their specialised work meant they were rarely needed in large numbers. Despite the longevity typical of such locos and the arrival of the diesel alternative, some British 0-4-0Ts were built as late as 1953 (to an LMS design).

The LNER acquired some 77 examples from the five larger constituents (including seven tram locos). Almost half were from the NBR (many attached to wooden tenders) and most of the remainder were from the NER and GER. Some 43 survived to Nationalisation (1948), including 33 of the NBR's 35 locomotives. The LNER added no less than 63 0-4-0Ts, mainly in the form of single-manned Sentinel locos. 59 of these survived into British Railways ownership.
