On Sunday 25th June 1967, Bristol Omnibus Company Limited (BOC) renumber their network of routes in the Gloucester and Cheltenham areas. At this time Service 112 running between Gloucester, Staunton, Hanley Swan, Malvern Wells, Great Malvern, and Malvern Link, became Service 572.
Service 112 had traditionally been operated by Bristol built double-deck buses, but six months before the service was renumbered, on Sunday 22nd January 1967, the route was converted to one-man operation and single-deck Bristol MW buses replaced the double-decks. The exception was the morning peak-time journey that continued to use a double-deck for a few more years due to the large number of school children it carried.
On Sunday 15th October 1972, all Service 572 journeys running on a Sunday were withdrawn, and cuts were made to the service on other days of the week.
From Saturday 2nd October 1976, at the request of Hereford and Worcester County Council, additional short-working Service 572 journeys between Malvern Wells and Malvern Link were introduced to partly replace cuts made by Midland Red Omnibus Company Limited (MROC) when they closed their Malvern depot. In addition, Service 575 was introduced as a variation to Service 572, running via the former Service 144 terminus at Upper Welland Turn. Bristol OC were not ready to take on these additional workings in time, so they were run on their behalf by MROC as a “temporary†agreement, which ended up lasting until Friday 12th January 1979.
After MROC ended their involvement on the route, Bristol OC made some minor adjustments to the timetable of their workings and continued to operate it for a few more years. In 1983, Bristol Omnibus Company Limited (BOC) was broken up, with operations in the Gloucester, Cheltenham, and Stroud areas passing to the newly formed Cheltenham and Gloucester Omnibus Company Limited. It is not clear is Service 572 was still operating at this time.
