Two class 710s continue to operate in passenger service seven days a week alongside the 3x4-car Class 378s which continue to operate the 30-minute interval 'temporary timetable'. This means that every 90 minutes there is a 30-minute gap in service. To help identify when these gaps occur, there is a list of working & cancelled unit diagrams on the BGORUG website: barking-gospeloak.org.uk/documents/20190528_Unit_Diagrams.pdf. This will be updated shortly to show the reinstated weekend diagrams. It should be remembered that the Class 710s are still suffering occassional minor faults and so some trips may be cancelled while these are dealt with.
It could be a few weeks yet before TfL are able to reinstate the full December 2018 timetable with Class 710 units.
