With a horn fanfare from the driver, 66423 passes Charlton-on-Otmoor on 16 July 2026 with the 4Z46 17:39 Daventry to Wentloog Tesco liner. This had left Daventry an hour late, but had managed to claw back some time, and was only 29 minutes late here. I have missed this train on a couple of occasions due to either late running or cancellation, so this was a change of fortune. Also, it is a well loaded train, which is not always the case.
