RETB Banavie North

Welcome to scot-rail.co.uk, Scotland's online railway community. The group is for any rail enthusiast interested in the railways and trains of Scotland. It not only consists of the wiki that you're reading now, but a busy online forum and mailing list, which is accessible to anyone who registers.

Introduction

Banavie Signalling Centre has two workstations for controlling the RETB Signalling on the West Highland Line:

  • The 'South' workstation controls Helensburgh to Upper Tyndrum, and Crianlarich to Oban
  • The 'North' workstation controls Upper Tyndrum to Fort William Junction, and Fort William Junction to Mallaig
Banavie North Workstation and Interlocking were modernised in November 2010.

Trials of RETB Next Generation commenced in April 2015, and previous system was taken out of use at the end of July 2016.

Banavie 'North'

This page describes the track layout and signalling. Stations are shown in bold type.

The Radio Channels noted below relate to the legacy radio system, and lineside signage has now been removed. The on-train RETB-NG equipment has auto tuning, only requiring a manual change between North and South at Upper Tyndrum.

RETB Signalling: Upper Tyndrum - Fort William Junction

Upper Tyndrum is the change over location between Banavie South and North RETB areas. On arrival drivers return the token, change radio channel, and follow the procedure for entering the new RETB area, before obtaining the next token.
