This page gives details of single-line block sections on West Country lines of the former London & South Western Railway, Southern Railway, and British Railways (Southern Region). For details of other West Country 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 19 September 2021. Further information will be added as it becomes available. Lines are listed geographically from east to west, and their individual sections are listed in line order. There is an alphabetical Index to Lines for quick access to individual lines.

Key to L&SWR/SR Methods of Working

EKT Electric Key Token (see note) METS Miniature Electric Train Staff ('M' type)
ETT Electric Train Tablet (type unknown) NSKT No Signalman Key Token
ETT 1 Tyer's No 1 ETT OES One Engine in Steam (train staff) [later re-named One Train Working (OTW)]
ETT 3 Tyer's No 3 ETT
ETT 6 Tyer's No 6 ETT TST Train Staff & Ticket
ETT 7 Tyer's No 7 ETT YARD Yard Working

NOTE: in many cases EKT working was introduced in British Railways days on lines which had passed from the control of the Southern Region to the Western Region. Unless otherwise indicated, any entry in the table below for EKT introduced after 1948 on a section west of Exeter may be assumed to be of the BR(WR) pattern. The BR(WR) key-tokens were made of alloy, whereas most of the BR(SR) examples were brass.

1 See Current Lines table for subsequent details.
2 Colyton was not a regular block post. During peak holiday periods additional ETT instruments were brought into use at Colyton under special arrangements to split the branch into two sections, but this was not normal switchable long/short section working. The additional instruments were removed in 1922 and Colyton was reduced to GF status thereafter.
3 Staff was round steel rod. SR records state green tickets, but it has been claimed that in BR days the tickets were blue.
4 Some BR(SR)-pattern brass key tokens ('A' configuration) exist for this section, but it is believed that these were manufactured for replacement work that was never done.
5 Worked by Acceptance Lever and track-circuit block. See Current Lines table for subsequent details.
6 Line from Meeth to Halwill Junction closed completely in 1965.
7 ETT replaced by OES 9-Jan-1966. Staff provided with Annetts Key 'A' for unlocking Padstow GF.
8 Line closed completely south of Furzebrook sidings in 1972. Worgret SB replaced by GF in 1976.
9 Lymington Junction abolished 1978 and branch extended as independent line to Brockenhurst. See Current Lines table for subsequent details.
10 Eggesford signal-box closed (flood damage) Nov 1967, new box opened 1969.
11 Renamed Barnstaple Junction 'B' in 1949.
12 Staff and Metal tickets provided with Annetts Key 'A' for unlocking Fremington GFs.
13 Staff provided with Annetts Key 'B' (paper tickets).
14 Tower Hill signal-box closed 1920, new box opened 1943.
15 Grogley Junction was only an intermediate ground-frame in the Wadebridge East - Boscarne Junction section.
16 One document mentions 'B' configuration, but some contemporary information suggests 'A' and a surviving key-less example (WR pattern alloy) has traces of red paint.
17 Example of these tablets which have been sighted are marked 'Torrington Jct' rather than just 'Torrington'.
18 Totton SB closed 1982 and section then converted to TCB working to Eastleigh panel.
19 Altered 9-April-1935. SR pattern key-token, but alloy not brass (originally?).
20 ETT replaced by EKT 25 July 1954 (WR pattern key-token)
21 According to L&SWR Instruction 88/1892 the TS&T section extended to both Chard Town and Chard Joint. Nothing is known about the working between the original L&SWR and GWR boxes at Chard Joint. See the Chard Branch page for more details.
22 Formerly the ex-GWR St Budeaux Ferry Road signal-box
23 Originally triangular wooden staff (varnished), but replaced at unknown date by round steel staff
24 An example of a 'Marchwood - Fawley' Key Token has been sighted which was alloy, 'D' configuration notch, square hole in a round handle with red band. Another example was brass (bronze?), 'B' configuration notch, with uncoloured square handle and hole. It is not known from which periods those examples originate.
25 Line singled Amesbury - Newton Tony 25-Oct-1953. Line singled Newton Tony - Newton Tony Junction and Newton Tony Junction abolished 17-Oct-1954.
26 ETT replaced by EKT 26-May-1954 (WR pattern key-token).

45 ETT3 replaced by ETT6 10-July-1960.
46 ETT replaced by EKT 10-March-1952 (WR pattern key-token).
47 Although some examples exist of Camelford - Delabole tablets re-engraved as Camelford - Port Isaac Road, photographic evidence suggests that Delabole was still a block post when the line closed and no formal record has been found of any earlier closure and amendment to the block sections.
48 Although ETT3 was in use by 1923, there is circumstantial evidence that a different pattern may have been used initially.
49 Barnstaple Junction 'B' signal-box closed 1971 and section extended to former 'A' box renamed 'Barnstaple'.
50 Line from Barnstaple Junction West to Ilfracombe opened in 1874 as single-track, but all doubled 1889-91 except for Barnstaple Junction West to Pottington.
51 In 1873 new signal-boxes were erected at all the intermediate passing-loops and block working introduced (as far as Umberleigh) using the single-line variant of Preece's 3-wire instruments, but the relevant L&SWR Instruction 133/1873 makes no mention of TS&T working. However the abolition of TS&T working was mentioned specifically in connection with the subsequent doubling of various sections of the line in 1883 and 1890. Consequently the situation prior to 1892 is unclear.
52 The actual divergence of the branch was at Dunmere Junction ground-frame, within the Boscarne Junction - Bodmin North section.
53 Line from Hurstbourne Jcn to Fullerton Jcn singled in 1913 and closed completely from Hurstbourne Jcn to Longparish in 1934.
54 According to L&SWR Instruction 601/1884 Tipton St John became a staff post at noon on 31-December-1884, but its prior status is unclear. The early status of Ottery St Mary is also unclear, as it was not listed as a staff post in 1892 yet appears to have had a passing-loop by 1889 (if not from opening).
55 The status of the signal-boxes at Woodbury Road and Lympstone during the period of TS&T working is unclear.
56 L&SWR Instruction 140/1893 depicted the Tresmeer-Otterham staff with a vertical oblong and the Otterham-Camelford staff with an horizontal oblong, but it is unclear how these 'oblongs' differed in practice.
57 Renamed King's Nympton in 1951.
58 The status of Bideford Junction box, located between Instow and Bideford, is unknown but it may have acted as an intermediate block, but not staff, post prior to 1894.
59 Renamed Ringwood on 20-Jan-1929 (when Ringwood East reduced to GF status).
60 Various sources suggest station originally named Hearne, or Hearne Bridge and renamed Hearne in 1888, and renamed Hurn in 1897.
61 In 1886 Christchurch East and West boxes were closed and replaced by a new Christchurch Junction box, in readiness for the opening of the new line from Lymington Junction via Sway. The station was reduced to a goods depot and replaced by a new station further to the west.
62 Station opened as Bournemouth in 1870, renamed Bournemouth East in 1874/5. Replaced in 1885 by new Bournemouth East station further west, renamed Bournemouth Central in 1899.
