Further increases in the volume of goods handling at the port were restricted by the docks inability to handle the new

British Railways was modernising freight distribution, with the former bespoke creation of manually loaded wagons being replaced by larger, bogeyed bulk-freight wagons that were automatically loaded. This resulted in a need for both larger yards to handle the larger wagons, and fewer yards as high speed freight traffic ran between them to reduce speed of delivery for the customer. BSC was becoming BR's most important customer, with coal traffic quickly falling.

landfill site to the west, along the lines of the PTR&D towards the

However, British Rails biggest problem was the 1.7million tonnes of raw iron ore required to be transported by rail to Llanwern Steelworks. Marshalling 27 × 100-tonne iron ore tipplers, the train was initially headed by three Class 37/0's, which continually caused problems with their couplings. The amount of power was required to climb ''Stormy Bank'', located just west of Margam, where the train would only reach at the top. Eventually replaced by two Class 56's, drivers reported that this combination could reach . After experimentation with two refurbished Class 37/7's, the company specially hired-in National Power
