Ilford Depot. Ilford Depot is a traction maintenance depot located in Ilford, Greater London, England. The site is used for train stabling and maintenance by Greater Anglia, Elizabeth line, London Overground and Alstom.

Location

The depot is situated on the Great Eastern Main Line and is on the north side of the line to the east of Ilford station, between that station and Seven Kings railway station.

History

Facilities for an engine pit at Ilford Goods Yard were first provided in 1889 by the Great Eastern Railway. With burgeoning commuter rail traffic, a three road engine shed was provided next to Ley Street which opened in 1901. A fire in May 1909 saw a number of locomotives damaged but repairs were authorised quickly and the structure repaired.

In 1903 a triangular junction was built just to the north of this site linking the main line to the Fairlop Loop.

The engine shed became part of the LNER in 1923. In 1931 the allocation primarily consisted of N7 0-6-2T locomotives and the site was adjacent to carriage sidings and a coal depot.

Plans were drawn up in the 1930s to electrify the suburban lines from Liverpool Street to Shenfield at 1,500VDC and late in the decade work was started on implementing this.  

Additionally plans were being made to extend the Central Line east from Liverpool Street and take over the Epping branch and Fairlop Loop.

Ilford was chosen as the location for the new depot and as a result the engine shed and carriage sidings were closed in May 1937. The site was cleared and the steel frame of the first shed was erected by June 1940 although it was not until 1949 that it had a roof.

As well as the site above the new depot required the land occupied by the link from Ilford to the Fairlop Loop which was subsequently closed on 29 November 1947. The link between Seven Kings and the Fairlop Loop was retained until 1956 for freight traffic before total closure after which the depot was extended further east towards .

Until a remodel in 2016, as part of the Crossrail works, Ilford TMD had four sheds:
 The first two of which were opened in 1949 for DC EMUs and were converted to AC in 1960. One was a six-tracked shed with four through-roads sheds and the other a three-road dead end shed; 
 The third building is the largest, opened in 1960 for AC EMUs, being a sixteen-road dead-ended shed. This was built on the land occupied by the Seven Kings to Fairlop Loop curve;
 The fourth building is a one-track through-road shed which was opened around 2000.

In 2021, a carriage washing machine was installed; it began operation in September following an investment of £1.2 million.

Allocation

The first EMUs allocated to the depot were 92 Class 306 EMUs which were fitted with sliding doors These operated services between  and  from February 1949.

The depot was allocated a 1914 North Eastern Railway (United Kingdom) EB1 class locomotive numbered 26510 as a shunter. This last ran on 4 November 1960 after which the shed was converted to AC operation.

Between 1952 and 1954 the depot hosted a number of Class 76 locomotives which were tested on local passenger and freight services.

During the 1960s as electrification was extended to Southend, Colchester, Clacton and Walton more EMUs were introduced and allocated to Ilford.

In the early 1980s the Class 306s were replaced by Class 315 units.

Around 1987, the depot's allocation included classes Class 302, Class 305, Class 307, Class 308 and 315 EMUs.

As these classes were withdrawn in the 1990s and 2000s they were replaced by Class 317, Class 321, Class 379 and Class 360.

In June 2017, new  trains began entering service in preparation for the opening of the Crossrail which led to the withdrawal of the Class 315 EMUs in 2022.

Facilities

Within the site is a sixteen-road shed, operated by Greater Anglia, which was formerly used for  maintenance of Class 321 units. Class 379 units were maintained by Bombardier Transportation on one of the roads, with Class 360 units maintained by Siemens Mobility on another. 

On introduction of Class 710 and Class 720 Alstom Aventra in 2019/20, all maintenance staff and facilities were transferred to Bombardier Transportation, which was acquired by Alstom in 2021.

A six-road overhaul and refurbishment shed is present, with three roads being electrified. In 2024 this building is used for light maintenance and exam work for the Class 345 Aventra and Bombardier Electrostar. A wheel lathe is present.

2023 Allocation
As of 2023, the depot's main rolling stock allocation consists of:
 Class 720, leased by Greater Anglia 
 Class 710, leased by London Overground
  Class 345, leased by the Elizabeth line

In 2023, there were two Class 08s on site used for shunting purposes. 08 700 is owned by Harry Needle Railroad Company and 08 573 is owned by RMS Locotec; both are contracted to Alstom.
