One locomotive became Metropolitan Railway No.1 and was a replacement for A Class No.1 which had been scrapped after an accident. The other locomotives were numbered 77 to 82. Number 77 is known to have been fitted with condensing apparatus. It is likely that condensing apparatus was originally fitted to the whole class, but later removed.
Displacement
The E Class were displaced from the main passenger trains by the 4-4-4T H Class in 1920, moving to lesser jobs such as trains on the Chesham branch, goods trains and engineering duties. Following the Second World War one E Class locomotive was regularly stationed at Rickmansworth station to cover a failure of LNER locomotives working Metropolitan Line trains north of this point.
London Transport
The first locomotive was scrapped in 1935 before it could be given a new London Transport number, something that only four locomotives would receive. No.1 became L44, while numbers. 77, 80 and 81 became L46–L48.
Preservation
L44 had the honour of working the last steam-hauled LT passenger train in 1961, and survived in use until 1965; it is now preserved at the Buckinghamshire Railway Centre. L44 was saved from being broken up for scrap by the endeavours of a 19 years old London Transport Mechanical Engineering Apprentice, who started the Met Tank Appeal Fund in 1962. The objective was originally to save the only remaining 0-6-2T 'F' Class locomotive numbered L52 in the London Transport fleet. LT offered this locomotive to him for £500. The Met Tank Appeal Fund raised just over £1,000, but when Jim went to hand over the cheque he was advised that an inspection had revealed a cracked mainframe, and the locomotive could no longer be 'steamed' and was therefore no longer suitable for preservation. However he was offered L44 in its place for the sum of £450. Jim was helped by committee members of the London Railway Preservation Society, and a locomotive fitter named Gerald Fitzgerald. The LRPS had storage for the Locomotive at Bishops Stortford, and also at Luton where it was subsequently moved to, but the Quainton Railway Society offered a secure and permanent base for it at their newly established museum in Buckinghamshire, and L44 moved there in the mid-1960s. No. 1 was maintained in main-line condition and made occasional forays onto its old home lines during the "Steam on the Met" events which took place between 1989 and 2000. It received a full overhaul in 2001. In 2007 No. 1 made its first visit away from Buckinghamshire Railway Centre since the 2001 Heavy Overhaul, arriving at the Bluebell Railway on 24 July in order to take part in the "Bluebell 125" celebrations. While there it was paired with four original Metropolitan Railway carriages which have been restored by the Bluebell. During August 2008 it visited Barrow Hill and in October 2008 Llangollen, to participate in their heritage events. In 2010 an appeal was launched to fund the restoration of Number 1, and to fund its continued upkeep for the following ten years to enable it to participate at many more heritage events In 2013, for the 150th Anniversary of London Underground, No. 1 was loaned to the LT museum for several trips between Olympia and Moorgate via Edgware Road on successive weekends in January of that year to honour the actual anniversary of the first Underground journey from Paddington to Farringdon on 9 January 1863. The train was made up of Metropolitan Locomotive Number 1, Metropolitan Railway Milk Van number 4 and the Metropolitan Railway Jubilee Carriage 353, both the property of the London Transport Museum. Coupled to these were the set of four 'Ashbury' Coaches of 1898 and Metropolitan Electric Railway Locomotive Number 12 Sarah Siddons, owned by London Underground Limited. Several preservation bodies were involved in providing or restoring the rolling stock for the event and the operation was given added impetus by the enthusiastic support of the London Mayor Boris Johnson and his commissioner of Transport for London, Sir Peter Hendy CBE, himself a Transport enthusiast.
