This page gives details of single-line block sections on the lines of the former Somerset & Dorset Joint Railway (S&DJR) until final closure of the S&DJR to all passenger traffic in 1966. For further information on the general subject of single-line sections, and details of other West Country railway companies, please see the Introduction page.

This page was updated last on 09 February 2012. Further information will be added as it becomes available. Sections are listed in line order. There is an alphabetical Index to Lines for quick access.

The S&DJR single-line sections have been the subject of greater research than some of the other lines covered by RailWest. Therefore it has been possible to provide a more detailed list covering the complete period from the first widespread introduction of Electric Train Tablet working to the S&DJR in 1886. Further background information can be found in the separate RailWest pages about S&DJR Block Working.

The S&DJR made considerable use of Tyer's No 1 ETT equipment and a few sections remained equipped with those instruments until early British Railways days. Configuration arrangements for No 1 tablets were different from later patterns, and consisted of a varying number of notches of different shapes/sizes in different locations around the edge of the tablet. The 'Configuration' entry for ETT 1 sections in the Table of Sections below gives the number of notches (where known) as 'XN' (eg the entry '2N' means '2 notches').
