This page gives details of single-line block sections on current Network Rail lines in the UK West Country. It does not cover private 'heritage' railways.

Information is provided for the period from about the late-1960s onwards up until about 2012, but it is hoped to include details right up to the current day in due course. For older details, including lines which had closed by about 1970, 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 04 February 2017. Further information will be added as it becomes available. Lines are listed geographically from north-east through south-east to south-west, and their individual sections are listed in line order. There is an alphabetical Index to Lines for quick access to individual lines.

The details provided here for single-line sections on current lines are different from those on the other RailWest pages for earlier periods. In most historical cases single-line sections occured on dead-end branches or distinct cross-country connecting lines, usually with signal-boxes at each end of the sections. Modern sections often are controlled remotely by a power signal-box many miles away. For identification purposes this page describes the limits of each single-line section by using the historical name for each junction or other location, even though no signal-box may exist there any more. There are also now many sections of single-line in the middle of double-track main lines, where service frequency or other reasons do not warrant the expense of maintaining two tracks. Where sections are controlled remotely the name(s) of the controlling signal-box(es) (where known) is given in the 'Notes' column.
