When the PRS acquired the line, the intention was to work the line with British locomotives and stock. However, enthusiasts from other railways and preservation societies had already acquired almost all of the serviceable ex-BR locomotives – all that was left was a collection of rusting hulks. Apart from 73050, the society's locomotives were mostly small, industrial shunting engines and therefore not suitable for the round trip. Ex-BR rolling stock was also in very short supply following the disposal of most pre-nationalisation (pre-1948) stock. The PDC, having paid out a considerable sum of money for the line, was anxious that trains should start running as soon as possible – certainly before the opening of the new Nene Park in 1978. However, with the PRC's lack of stock and locomotives this looked highly improbable.
