This document provides the system description for the Tie-FenLock 100 Depot Control System (DCS) for use in depots, yards and other non-mainline applications. The Tie-Fenlock 100 DCS is the entry level system of the Tie-Fenlock series, providing a simple and compact depot control 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)
