IntroductionBanavie 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
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.

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.

Tokens to Fort William Junction can only be issued by Banavie SC with the co-operation of Fort William Junction signal box.
Fort William station area has colour light signalling and is controlled by a panel in Fort William Junction signal box.
Trains can enter the RETB system and obtain a token anywhere in the Fort William Junction TCB area. Authority to proceed towards Spean Bridge or Annat will be the clearing of the appropriate section signal (FW23 or FW25) at Fort William Junction.
