Another thing worth noting was the community involvement in the Avoncliff shelter project (see link above.) Judging from what one guy at the station was saying, similar sentiment exists along the Oxford-Banbury line (an example being the local partnership deal that brought about the Sunday services), and perhaps FGW▸ could harness that in the same way in this particular instance.
Tackley and nearby Heyford have both been adopted by local people. FGW has a service delivery manager for the line and he works closely with the county council's rail officer.
There is an Oxford Canal Line Partnership (you may have seen the station signs have a special logo) and this brings together the county council, First Great Western, British Waterways, Cherwell District Council and local businesses. It aims to promote use of the railway and encourage people into the countryside through posters, leaflets and service or station improvements. The Sunday service came about as a result of the Partnership and its achievements have been recognised at national awards.
