Yesterday I was on 1643 Liverpool to Euston formed of 805008 and 805009. Shortly before departure it was announced it wouldn't be stopping at Runcorn. My first thought, as the train was overcrowded, was that they were limiting local passengers on the train and we would make a stop to pick up, but no, we passed through without stopping. AWC journey check showed it as 'follow the failure of a previous train'. I think the 805 provision was a late set swap, but was wondering if the 805s aren't permited to stop at Runcorn?
