Gospel oak to barking is a route that uses class 710’s now but I think DTG would have difficulty licensing these trains so I think if they were to make this route they should use class 378’s.Gospel oak to Barking line carries both goods and London overground trains it is 13 miles and the electrification programme was completed in 2018 Here is some info from Wikipedia The Railways Act 2005 abolished the franchise and gave the operation of passenger services to Transport for London (TfL). In 2005, TfL started funding a small number of additional peak time and late evening services to relieve the worst overcrowding. TfL took full control in November 2007 introducing improved late night and weekend services, and staff, ticket machines and Oyster equipment at all stations. The frequency was increased to three trains per hour during morning and afternoon peaks and the line was included on the Tube map for the first time. In 2010 eight new Class 172 Turbostar diesel trains replaced the Class 150 units, with two 23-metre coaches and the option to introduce a third coach.[8][9] The service frequency was increased to four trains per hour in January 2011.[10] Given the completion of electrification in 2018, new electric Class 710 trains were supposed to run from March 2018. The delivery of the trains was delayed by the manufacturer however and has been delayed, and it is not known when these units will enter service.[11][12][13] Due to the class 172 units being needed by West Midlands Trains, three Class 378 units (378 206, 378 209 and 378 232) have been moved from other parts of the London Overground and shortened down from five to four carriages to provide an interim service until the class 710 units enter service. However, 6 trains are needed to be able to run a full service, so from 15th March 2019 (the day the last class 172 units left London Overground) the frequency on the line was halved to two trains per hour.[14] Here are some pics Class 378 144 at gospel oak Class 378 232 passing south Tottenham Class 378 232 passing approaching leyton stone high road Class 710 Class 66 heavy goods train
