This document provides the system description for the Tie-FenLock 400 Depot Control System (DCS) for use in depots, yards and other non-mainline applications. The Tie-FenLock 400 DCS is the most
advanced system of the Tie-FenLock series, providing a full signalling solution.
Locally Operated Point System (LOPS) – points are switched over by plunger local to a turnout.
Points Setting Panel (PSP) – each point end is operated using an individual switch on the panel.
Route Setting Panel (RSP) – similar arrangement to the 200 system. However, it includes axle counter train detection and all points in a route are operated by a single button.
Fully interlocked signalling system operated by a single control person, via a visual display unit (VDU).
The current UK installations are:
British Steel, Scunthorpe. Tie-FenLock 100 installation with 350 point ends (1989-90)
Bombardier Central Rivers Depot, near Derby. Tie-FenLock 300 installation incorporating 29 pointends, point position indicators throughout and axle counters (2001)
Alstom Golders Green Depot, London. A London Underground application (2006)
Chilterns Banbury Depot, Banbury. Tie-FenLock 400 installation with 7 point ends, fully interlockedwith signals and interfaced to the mainline (2016-17)

Fenix Rail Systems recommend the Tie-FenLock 400 DCS for its centralised depot control features, flexibility, low operating costs, legacy support and standardised interface to Network Rail (NR) mainline interlockings and Depot Personnel Protection Systems (DPPS).
