The Challenge For Softech

A new wheel Lathe depot was proposed to be located by the old Clacton Steam Shed off the unused approach road area from the existing Dead-End Siding (Shunting Spur), towards the current carriage sidings (Up Carriage Sidings) to service the GA fleet including Stadler 12 Car and Alstom 5 Car services.

The Signalling at Clacton on Sea was recently altered (March 2021) by Network Rail which abolished Clacton Signal box with control and indications transferred to Colchester Signal Box.

The Locally Operated Points System (LOPS) and Depot Protection System (DPS) were to exchange a number of functions to control entry and exit to the Wheel Lathe Road. Point operations within the depot was to be controlled by a LOPS under the control of the Depot Responsible personnel.

The entry and exit of trains into the Depot was very challenging to integrate with the existing signalling system without updating the existing signalling.

Softech’s Solutions

Softech undertook Feasibility study and Options Development at ES3. A Scheme Plan was produced for final option in ES4, along with other supporting documents. Many site surveys were carried out, including Signal and Signage Sighting reports during ES3 and ES4.

The Result

The proposed wheel lathe facility was built on a new southbound spur from the dead-end siding (Shunting Spur) back towards the carriage sidings to enable protection to trains and wheel lathe operatives, by the locking of power operated points into the carriage wash road away from the dead-end siding (Shunting Spur).

The works included a new wheel lathe building with locally operated points system (LOPS) for the control of train movement into, within and out of the facility. LOPS was to be interlocked with DPS (Depot Protection system).
