I've decided to base myself at Corfe Castle, Dorset, for the week, primarily to shoot images of the heritage railway, but also to learn something about the running of a single line system.
Several times over the past two weeks, I've seen a pouch with a hoop passed to the fireman of a steam train by the signalman as it enters a section of line. This is called a 'staff' which contains the 'token', which the driver needs to enter the next section of track. Each token is specific to the section of track to which it belongs, and gives the driver the authority to enter the next section of single track, knowing it is clear of other trains, whichever direction they may be running.
The image shows the signalman holding the staff aloft for collection as 80078 enters Corfe Castle station this morning. The castle is clearly visible in the background.
