This page gives details of single-line block sections on West Country lines of the former Great Western Railway and British Railways (Western Region). For details of other West Country railway lines please see the Register of Single-Line Sections page. For general information about the block working of single-line sections please read the Introduction to Single-Line Block Working page.

This page was updated last on 22 October 2014. Further information will be added as it becomes available. Lines are listed geographically from north-east to south-west, and their individual sections are listed in line order. There is an alphabetical Index to Lines for quick access.

Key to GWR Methods of Working

C2 Table C2 Working see Note OES One Engine in Steam (train staff)
EKT Electric Key Token OTW One Train Working (train staff) see Note
ETS Electric Train Staff TST Train Staff & Ticket
ETT Electric Train Tablet (Tyer's No 7?) USC Under Signalman's (or Shunter's) Control see Note
NS 'No Staff' Block YARD Yard Working
NSKT No Signalman Key Token
 

NOTE:

C2/USC. During the 1960s onwards a number of goods-only lines previously worked by OES were placed under the control of a nominated person (usually a signalman or shunter) and the train staff was abolished. Later these lines were listed in a new Table C2 in the Sectional Appendix and thereafter the method of working was described simply as "Table C2".

OTW. Originally this was simply OES described by another name after the demise of steam locomotion and the term is used on this page for any later sections specifically listed as OTW in BR records. More recently again it has been adopted to indicate one train working without a train staff, but it is not used in that context here.

Notes:

1

Summer section only, abolished 12-June-1960
2 Winter section only, abolished 12-June-1960
3 Summer section only, abolished 12-June-1960 and line converted to siding
4 Lydford was spelt Lidford on the staffs
5 Staff was varnished wood (no trace of colour) with Annetts key (no configuration nib) in BR(WR) days - see picture. The line closed on 15-Feb-1951, but there was very occasional use for some while afterwards and it is not known if the staff remained in use during that time.
6 Limpley Stoke North SB reduced to GF in 1927 and block section control passed to former South box
7 Dunkerton and Dunkerton Colliery SBs closed during the Great War and it is unclear if one or both re-opened afterwards for a short period, so the status of the sections is not known.
8 The branch opened from Watchet Junction (later renamed Norton Fitzwarren Junction) to Watchet in 1862 and was extended to Minehead in 1874.
9 Minehead SB closed 1966 and double-track to Dunster converted to two independent single lines.
10 'Switching-out' facility removed from Kentsford SB in 1952 upon closure of Washford SB.

11

In 1970 the line between Norton Fitzwarren Junction and Bishops Lydeard was singled, both SBs were closed and thereafter the junction for the branch was further east at Silk Mill Crossing.
12 It is believed that the change from ETS to EKT may have taken place when Frome West ceased to be a block-post in 1933.
13 Mells Road SB opened 1910 to replace separate North and South boxes
14 From 1932 onwards Oakwood, Pill and Portbury Shipyard all closed together for long section working from Clifton Bridge to Portishead only.
15 One source suggests that ETS was replaced by EKT in 1954, but another source records the section as still ETS in 1961, and it is rumoured to have remained as ETS until closure of Thorverton signal-box in 1964. It was recorded as USC by June 1966.
16 USC by June 1966
17 Supplemented by Block Telegraph 1882-1893, staff configuration details uncertain pre-1893
18 In 1965 line cut back to Crockham Siding and worked OES initially, then (by June 1966) as 'Table C2' working by person-in-charge at Heathfield until final closure in 1968
19 1894 Working Time Table says semi-circular blue staff, but 1898 WTT says hexagonal blue staff
20 The Tolcarn Junction to Shepherds section of the line used part of the route of the earlier Treamble Branch, which subsequently diverged at Shepherds
21 The Perranporth line closed 4-Feb-1963, but a short section from Tolcarn Jcn to Trevemper Siding remained in use until 28-Oct-1963
22 St Agnes was probably upgraded to a block post in 1909, but certainly by 1914
23 USC by June 1966, C2 by Sep 1969
24 Named Portland Junction until 1899
25 Short/Long section working after switching-out facilities added at Rodwell in 1931, until Rodwell closed in 1954.
26 References to 'Portland' signal-box pre-1905 are for the old station, those for 1935 onwards are for the new station.
27 When the first signal-box opened at Rodwell in 1892 it was an intermediate block post, but not a staff station.
28 Bodmin General was marked as Bodmin Town on the staffs.
29 Bodmin Road - Bodmin General converted to EKT on 28 Dec 1950. Bodmin General - Boscarne Junction converted to EKT 4 Nov 1964.
30 This note is not used.
31 In 1924 Blackwater Junction North and East signal-boxes were closed and the branch from St Agnes continued eastwards as an independent single line to Chacewater.
32 Details for this line are complicated by the break at Carpella during 1909-22. Some block posts existed at places without signal-boxes at some times. 'Best efforts' have been made to provide a comprehensive record, but only the post-1950 details are known with some certainty.
33 From 26 Aug 1912 onwards the block section south of St Dennis Junction started at St Dennis Junction GF.
34 By Apr 1965 St Dennis Junction GF to Parkandillack was closed temporarily until further notice and EKT working suspended.
35 Staff was round, metal with key-token end. Key had both 'A' and 'D' configuration notches (reason unknown).
36 There are two surviving examples of a metal Annetts key with 'T' handle labelled for the branch. It is not known if these were used as the train staff at any time or perhaps were emergency spares and/or GF release keys.
37 There was an intermediate block post at Staverton, but it was not a staff station.
38 Photographic evidence (surviving relic) shows a red, wooden staff (apparently octagonal) with a 'C' Annetts key at one end and a 'C' EKT key at the other end. 
39 The branch closed to all traffic beyond Upwey on 1-Dec-1952. Upwey Jcn was renamed Upwey & Broadwey, whilst Upwey became Upwey Goods. Although OES working was retained for the line to Upwey Goods, it is possible that it was downgraded to 'siding' status prior to final closure on 31-Dec-1961.
40 This staff was a rather crude item made from an old Hallatrow - Radstock West key token sandwiched between two pieces of wood - see picture.
41 Listed as "Track Circuit and Interlocking Lever", believed to be a form of "Direction Lever" system. Normal BR(WR) double-line block instruments were provided also.
42 Although a 'D' configuration token 'East Anstey - South Molton' has been sighted at auction, it is believed never to have been implemented as Bishop's Nympton & Molland signal-box remained in use until the line closed in 1966.
43 The intermediate SB at Thornfalcon (opened as Thorne 1892, renamed 1902, closed 1912) was not a staff post, so has not been listed. Hatch SB opened 1892, but did not become a staff post until circa-1908.
44 Chard SB opened 1892, renamed Chard North 1896, renamed Chard circa-1917/23, renamed Chard Central 1950.
45 Passenger services ceased in 1962. It is believed that block working methods remained unchanged until Ilminster and Chard SBs closed in 1964.
46 Surviving examples are inscribed simply 'Yeovil - Yeovil Town' with no mention of 'Pen Mill'.
47 Listed in TNA file RAIL 937/11 as 'OES with Pilot Board' 1857 to June 1868, then 'OES with Train Staff' until March 1881.
48 ETS working was introduced by Nov 1893. The new SB and revised layout at Bridport was ready in mid-1894. It is assumed, but not certain, that the branch was divided into two ETS sections in 1893 rather than 1894.
49 In 1906 a section of the Yeovil Branch between new junctions at Curry Rivel and Althelney became part of the new double-track main line from Castle Cary to Cogload Junction and it remains in use currently.
50 Prior to the introduction of ETS working, the SBs at Athelney and Montacute were block posts but not staff posts.
51 The North and South SBs at Yeovil Pen Mill were replaced by a single SB in 1937. The East and West SBs at Yeovil Town were replaced by a single SB in 1916.
52 Records indicate that a 'switching out' lever was installed at Hendford in 1927/8 and removed circa-1950, but there is no evidence that any form of long/short section working was ever introduced for the Yeovil Town - Hendford - Montacute sections.
53 In 1887 there were non-block signal-boxes at Praze and Nancegollan. Board of Trade records list the branch as being worked by train staff with block telegraph from Dec 1889, so it is possible that one or both of those SBs became block (but not staff) posts at that time. ETS had arrived by Aug 1896 and those SBs were converted to GFs. Nancegollan became a staff post in 1907, but became a GF again in 1908 when Nancegollan Crossing was opened.
54 This was a separate location from Nancegollan station. Some records call it Nancegollan Loop, it is believed that the signal-box was named Nancegollan Crossing, whilst surviving ETS are labelled Nancegollan Crossing Place.
