two signal boxes: the original Buckfastleigh box at the north end<br />

of the station which is currently out of use and Ashburton Junction<br />

(located at Totnes Littlehempston), which is the former GWR box<br />

from Cradley Heath East in the West Midlands. All the signalling<br />

on the railway is based on typical GWR practice. The telephone<br />

system upon the railway consists of an omnibus circuit provided<br />

for the whole of the line, with signal post telephones installed for<br />

each operational signal box.<br />

Having arrived at Totnes Littlehempston station, Mr Trevor<br />

Hodgson gave a structured safety briefing and overview of the<br />

railway signalling and telecommunications systems employed. In<br />

one large group, we undertook a tour of the site including the<br />

viewing of the new south ground frame, the station and Ashburton<br />

Junction signal box under restoration. At the north end of the site<br />

is the ground frame that currently operates the signal for the<br />

station platform line, along with the points to allow locomotive<br />

run-round and for the through passenger trains that arrive from<br />

Network Rail infrastructure each operating season.<br />

After a good look around Totnes Littlehempston station and a<br />

visit for some to the nearby Rare Breeds Farm, we boarded the<br />

next steam hauled passenger train in order to get to Staverton<br />

station, where we visited the original 1911 crossing box, released<br />

from the nearby Bishops Bridge signal box. The Bishops Bridge<br />

signal box and passenger passing loop were installed and<br />

commissioned in 1999 having previously been located at Athelney<br />

in Somerset, with further alterations to the Dock Siding and<br />

Staverton level crossing installed and commissioned in 2005. The<br />

signal box itself is fitted with a GWR stud frame and has a closing<br />

lever installed. The block working is by electric key token (EKT) to<br />

Buckfastleigh and by train staff (with ticket working for special<br />

events) to Totnes.<br />

When Bishops Bridge signal box is closed, the railway is<br />

operated under the one-engine-in-steam principle with a longsection<br />

train staff. The signal box switching-in arrangements are<br />

such that the long section train staff releases the closing lever,<br />

which in turn releases the short section train staff to Totnes and<br />

the token instrument release staff. The token instrument release<br />

staff is an Annett’s key at one end and a key token at the other.<br />

Once released, the token end is placed in the token instrument to<br />

Buckfastleigh, which then puts the token section in phase.<br />

Switching out is the reverse of the switching in arrangements,<br />

with the long section train staff being released once the closing<br />

lever is reversed. Whilst walking around Bishops Bridge observing<br />

the signalling infrastructure, it was noted that an upper quadrant<br />

signal arm exists on the end of the passing loop. Upon closer<br />

investigation, the words “Reading Signal Works” were found to be<br />

on the spindle casting and we were informed that it had previously<br />

been located at Neasden South in London.<br />

In order to board our special train for the return trip to<br />

Buckfastleigh, we moved back to Staverton station, where once<br />

again the Section Chairman was allowed in the driving cab. Back<br />

at Buckfastleigh, we were treated to a superb buffet lunch in a<br />

converted wooden railway coach at the station, before continuing<br />

our tour of Buckfastleigh North and South signal boxes and the<br />

extensive locomotive engineering facilities. This latter is a major<br />

revenue-earner for the railway, undertaking tyre installation and<br />

renewal for other railway companies, both mainline and heritage.<br />

The visit ended with thanks given to Trevor Hodgson for his<br />

efforts in arranging the day’s events.<br />

This was a truly enjoyable weekend and we look forward to<br />

many more.<br />
