The thing that surprised me most about the Gloucestershire Warwickshire Railway was the views from the train window. I hadn't realised it was in such a pretty part of the world.
It is now in it's middle age as a heritage line; old enough to attract more than just hardened rail fans, but still growing. At the time of my visit (2016) 1t ran between Cheltenham Race Course and its main base at Toddington with short DMU rides available further northwards to the site of the former Laverton Halt
Since then they have extended the line to Broadway, with the eventual aim of restoring it all the way to Honeybourne.
For timetables, ticket prices and much more, please see the GWSR's official site.
As well as the heritage line, there is plenty to see and do at Toddington. There is the official museum housed in an old brake coach, together with two other collections of Railwayania and other ephemera.
There is also an the Engine Shed Viewing Area, a narrow gauge railway (not running the day I visited) and a number of historic vehicles.
The highlights of line include the Greet Tunnel, the second longest tunnel on a British heritage railway, and the Stanway Viaduct.
