Among friends and neighbours here in west Oxford there's virtually no perception of the important role of the railway in conveying vast volumes of deep-sea containers from/to Southampton, plus aggregates, automotive, industrial minerals, defence traffic (occasionally), scrap and infrastructure materials. When I tell them that on a typical weekday we can expect to see up to 48 freight trains through Oxford they think I'm overstating the significance of rail freight in keeping traffic off the notoriously-congested A34.
