Successes of the Group include:
* The renaissance of Hanborough and Pershore services. When the Group was formed, only two or three trains per day called at these stations.
* The retention of some direct InterCity trains to and from London following British Rail's stated intention to withdraw all such trains from May 1982 due to the poor state of the track.
* The gradual upgrading of the track, enabling faster trains to operate, has been achieved after pressure from the Group. * The re-opening, in May 1981, of Honeybourne station.
* The introduction in 1987 of a weekday mid-evening train from Oxford to Worcester and Great Malvern (now the 19.22 from Paddington to Hereford) to fill the previous long gap in services. In 1998, a further train from London (20.20) to Moreton-in-Marsh was added in response to requests from passengers and has now been extended to Worcester and Great Malvern.
* Pressure from the Group persuaded First Great Western to run the 19.22 from Paddington through to Hereford. Late running of this train often resulted in a missed connection at Worcester into the last train of the day to Hereford and road transport having to be arranged.
* The reinstatement in May 1993 of the through services to/from London which were lost in 1982. These trains were formed of air-conditioned Turbo stock and attracted considerable extra passenger evenue. As these trains began to show their age and, in some cases, were inadequate for the increasing passengers numbers, First Great Western were encouraged to replace them with 8 coach High Speed Trains and to arrange for the return of 5 Class 180 units. Most journeys beyond Moreton-in-Marsh from/to London are now operated by trains capable of running at speeds of up to 125 mph between Didcot and London.
* The withdrawal of closure proposals for Combe and Finstock stations in May 1994.
* The reinstatement of Sunday morning services throughout the year.
* Obtaining a concession in 2005 from First Great Western Link to hold the 1200 departure from Oxford to London by up to 5 minutes in the event of late running of the connecting Cotswold Line service from Great Malvern.
* Pressure from the Group over many years has resulted in the reinstatement in 2011 of 20 miles of double track, thus easing the operation of trains at busy times or when delays occur.
* Additional weekday services from London to Moreton-in-Marsh to, in effect, create an almost hourly interval service.
* The introduction by London Midland on 9th December 2012 of Sunday morning services between Hereford, Worcester and Birmingham New Street came following representations by the CLPG.
