Further to your answer to Question No: 2018/1860, I understand that you are mistaken in much of your reply. There have been no additional trains operating "temporarily" on the Barking to Gospel Oak line. The five trains in question (PIXC-busters) have operated since 2013 and until 19 May this year appeared in the published timetable. When these trains did not appear in the 20 May summer 2018 timetable, the Director of Rail gave an assurance that the trains would continue to run until the electric trains arrived in public service. However, these trains ceased to run after 29 June. This is because one of the eight 2-car diesel trains (172 002) that maintained the Barking - Gospel Oak service had been transferred to West Midlands Trains in Birmingham. The drivers' diagrams (duties) for these five trains were withdrawn on 1 July. Since then London Overground has not had enough rolling stock to run the current published timetable reliably, with 20 cancellations occurring on Sunday 22 July, for example. London Overground can clearly no longer operate the five trains in question, contrary to your assurances, so what can be done to sort out this service?
