Hi all, I am planning a trip to Crewe with my (also) train mad son and particulary interested in catching some 86,90 and 92 workings. Will be on station from 9.30 til 17.00 and I know a lot of freight goes on the avoiders, but is there a particular day from Mon to Sat where you might see more freight or are they all similar. Just need to know so I can book some (cheap !) advance tickets. Many thanks !
