The trains are part of Bombardier's Aventra family. The contract to provide 45 four-car trains was awarded in July 2015 and the trains were originally due to enter service in May 2018, although they have now been delayed until some time in 2019.[1] HistoryBackground and specificationsIn 2012, TfL announced its intention to procure a fleet of new, longer DMUs, as the {{BRC|172}} units then in service were unable to handle the passenger demand, causing overcrowding throughout the day. TfL issued a tender for manufacturers to supply eight three- or four-car trains.[2] However, this proposal was subsequently shelved when the Government announced that the Gospel Oak to Barking line ('GOBLIN') would be electrified, with proposals instead to purchase a fleet of new EMUs. TfL invited expressions of interest for a total of 39 four-car EMUs in April 2014, with 30 required for the Enfield Town, Cheshunt and Chingford to Liverpool Street routes, eight for the Gospel Oak to Barking, and one for the Romford to Upminster - all to replace older Class 172, Class 315 and Class 317 trains.[3] Since then the planned procurement was increased to 45 four-car EMUs, with the additional six units intended for the Watford DC Line. The intention is that the five-car {{BRC|378}} trains currently used on the Watford route will be cascaded back to the North London and East London Lines to allow for strengthened services. TfL issued an Invitation to Tender (ITT) in early 2015, and in June 2015 announced that Bombardier had been awarded the contract to build the new trains.[4] In July 2015, TfL announced that it had placed a £260m order for 45 four-car Bombardier Aventra EMUs, (with an option for 24 more four-car units plus further option to extend some or all units including option units to five cars). These are similar to the Class 345s that will be used by Crossrail, for use on the West Anglia Routes and the Watford DC, GOBLIN and Romford to Upminster lines, from 2018, to be known as Class 710.[5] The units will be delivered in two sub-classes; an AC-only version for use on the West Anglia and Romford-Upminster services, and a dual-voltage version for the Watford DC and GOBLIN services. Both versions will have all-longitudinal seating after the plan to have some transverse seats on the AC units was dropped. The AC only version will be maintained at Ilford TMD and the dual-voltage units at Willesden TMD.[6] In 2017, Transport for London put forward a proposal to procure nine additional Class 710 units to be used as capacity enhancers. These would cover 42 of the 249 additional vehicle options, and would be formed into three 4-car sets, one which would be for use on DC lines and two for the extended GOBLIN to {{stnlnk|Barking Riverside}}, and six 5-car sets for use on the NLL and WLL, allowing a cascade of Class 378 units to increase services on the East London Line.[7] IntroductionOn 25 April 2018, the Islington Gazette reported that the trains would be introduced three months later than scheduled due to delays in their testing.[8] On 20 June 2018 the Barking and Dagenham Post reported that that the trains would be in service by November 2018, "almost 18 months later than planned".[9] In November 2018, TfL said that they hoped the units would be in service by December 2018,[1] however, due to further technical problems experienced during unit testing, the units will not enter service until 2019.{{cn|date=December 2018}} In January 2019, TfL announced that three Class 378 trains would temporarily be deployed on the Gospel Oak to Barking line while continued problems with Class 710 are resolved[10], since leases on the existing Class 172 stock running on this line will come to an end before 710's likely introduction in to passenger service. Fleet detailsA total of 54 units totalling 222 carriages are to be built. This will consist of 48 4-carriage units and six 5-carriage units.[11][12]
