1923 worked at least 1 trip on the 5 this afternoon.
Meanwhile, OmniCity 4654 spent at least part of the day on 9/27a - but finished the day by becoming only the second example to work Stockton's service 6 and the only example to have worked it since the March change. Seen below in Stockton on the 1810 from Middlesbrough to Fairfield on the penultimate day of operation of that trip
