In railway terms Chard Junction seems to have had a bit of an identity crisis in the years since the 1967 singling. After that it was called simply 'Chard' and that name appeared on the box diagram, both there and at the adjacent boxes. From what I can see from photos the replacement panel had no name on it, but other items in the box and paperwork at the time still talked about 'Chard'. However the nameplate said 'Chard Junction' and that name seems to have had a resurgence recently. I don't know what, if any, name is on the new panel.
The loops are Gillingham, Chard Jcn and Honiton were fairly conventional, insofar as being signalled essentially for LH running, but with a bi-directional capability on one line (Up line for the frist two, Down line for Honiton). Tisbury Loop is different, being regarded as a Main line with a Loop (on the Down side) - first train to arrive always goes into the Loop, then the second train passes thru' on the Main - there are NO 'starting' signals on the Main.
I have compiled some notes about the line since 1967 at www.railwest.org.uk - it needs updating now to reflect the Axminster changes, and more in the coming months as the signalling is altered for transfer to Basingstoke. The former Sherborne box was demolished in Sep and Honiton will go in due course, as probably now will Yeovil Jcn unless someone manages to preserve it.
Apparently some UP direction signals are being installed at Crewkerne, as well as replacements for the Down ones which protect Crewkerne Gates AHB. I wonder if the former reflects an intention to sub-divide the single-line section for improved headway?
