Editing 2-4-4T (section)

==Examples==
This unusual wheel arrangement does not appear to have been used on the [[Main line (railway)|mainline]] railways in the UK. It was however one of the configurations used on the [[Mason Bogie locomotive|Mason Bogie]] [[articulated locomotive]]s, in the USA during the 1870s and 1880s. Five examples were constructed at the [[Mason Machine Works]] for the [[narrow gauge]] [[Boston, Revere Beach and Lynn Railroad]] 1883–1887. The railway subsequently received twenty-one further examples between 1900 and 1914, constructed by the [[Taunton Locomotive Manufacturing Company]], [[Manchester Locomotive Works]], and [[ALCO]]. Developmentally, there are two logical ways of reaching this wheel formula: to add a forward axle to a Forney locomotive to improve its ability to negotiate curves, or to add a second trailing axle to a Columbia design, notably in a 2-4-4(T) configuration to expand its coal capacity. 

Four 2-4-4T passenger locomotives were built by the Czechoslovak Škoda for Lithuania in 1932 and marked as Tk class. They were seized by the USSR in 1940, then by the Germans.<ref>Vitaliy A.
