sentences:  The North Island had been completely dieselised by the end of 1967, and the 1968 introduction of the DJ class diesel locomotives had led to the dieselisation of almost all of the South Island's services.However, the "South Island Limited" continued to operate with steam motive power, repeating the pattern in the North Island (where the KA and JAs hauled the express and relief expresses until 1965, nine to ten years after steam had been replaced on NIMT freight and the Wairarapa line by 1955–56).In the last years of the "South Island Limited", intermediate stops were increased to 21 but overall journey time reduced to 11 hrs 40 minutes.
