About SideTracked Caches
This cache belongs to the SideTracked series. It is not designed to take you to a magical place with a breath taking view. It's a distraction for the weary traveller, but anyone else can go and find it too. SideTracked caches have become a nationwide series of caches for public transport users. They are intended to provide quick cache-and-dashes at or nearby railway stations. Caches can be found close to stations of the national rail network and well as heritage railways.
