By 1966, "Western" diesels had taken over from the "Warships", and although not officially advertised as "The Bristolian" the train, now sometimes having 12 coaches, was still achieving the 105 minute schedule even with a stop at Bath included (the up route having been changed in 1961). In 1971 the route was again altered: both the up and down trains were routed via Badminton and called at the newly opened Bristol Parkway, and the load was limited to 10 coaches giving an overall schedule of 110 minutes. The final version of the loco-hauled "Bristolian" came about in 1973 with the introduction of air-conditioned Mark 2 coaches, and the replacement of the Westerns by Class 47 diesels.
