The '''Class EF1''' (''Electric Freight 1'') was a class of [[Electric locomotive|electrically powered locomotives]] built by the [[North Eastern Railway (UK)|North Eastern Railway]] from 1914. They were built to haul coal trains from the mines at [[Shildon]] to the docks at [[Middlesbrough]]. In common with other LNER electric locomotives, no classification was given to these locomotives until 4 October 1945, when nos. 3-12 were all classified EB1 (Electric Banking 1) although only no. 11 was actually modified for [[Bank engine|banking]].{{sfn|Boddy|Fry|Hennigan|Hoole|1990|p=93}} It was expected that all the locomotives would be similarly modified, but this did not happen, and the remaining locos were classified as '''EF1''' (Electric Freight 1).{{sfn|Boddy|Fry|Hennigan|Hoole|1990|p=93}}

==Proposed diesel conversion==
During the 1920s the coal traffic declined and some of the locomotives became surplus to requirements. In 1928 a plan was devised to convert one of them to a [[Diesel–electric transmission|diesel-electric]], using a 1,000 hp [[William Beardmore and Company|Beardmore]] diesel engine driving an [[English Electric]] generator. This plan did not come to fruition.<ref name="LNER info"/>

==Class EB1==
Electric traction on the Shildon line was discontinued in 1935 but the locomotives were retained for possible future use. Number 11 (later BR 26510) was rebuilt in 1941 for use as a [[Bank engine|banker]] on the [[Manchester–Sheffield–Wath electric railway|Manchester-Sheffield line]], and given the classification '''EB1''' (Electric Banking 1). Horsepower was increased from 1,100 to 1,256 and the twin [[Pantograph (rail)|pantographs]] were replaced by a single central one. In October 1945, all ten locomotives were classified as Class EB1. Although only one had been rebuilt, it was expected that rebuilding of the others would follow. Nos. 3-12 were renumbered as Nos. 6490-9 in the LNER's 1946 renumbering scheme. After nationalisation in 1948 they were renumbered again as 26502-11. In 1949, the plan to convert the remaining nine locomotives as banking engines was dropped and they were reclassified as Class EF1 (Electric Freight 1).<ref name="LNER info">{{cite web|url=http://www.lner.info/locos/Electric/ef1eb1.shtml |title=The NER Electric Bo-Bo Class EF1 & EB1 Locomotives |publisher=Lner.info |access-date=2013-09-08}}</ref>

==Final years==
The EF1s were withdrawn in 1950–51. In 1949, the EB1 (number 26510) was moved to [[Ilford]] Depot (Eastern Region) for use as a shunter.{{sfn|Boddy|Fry|Hennigan|Hoole|1990|p=93}} Number 26510 was transferred to departmental stock (as No. 100) in 1959 and withdrawn in 1964.{{sfn|Boddy|Fry|Hennigan|Hoole|1990|pp=95,97}} None of the locomotives were preserved.
