700043 approaches Sandy on 2 October 2019 with the late running 9J39 13:54 Peterborough to Horsham Govia Thameslink Railway service. These new units are too sophisticated for their own good, as when a National Grid problem in August 2019 caused the grid frequency to fall below 49Hz, they failed en-masse! Even worse, over half required a technician to come to their aid to get them started again!
