SELLA CONTROLS to replace Docklands Light Railway SCADA Solution

Stockport, United Kingdom – Systems integration specialist SELLA CONTROLS is pleased to announce the contract award by KeolisAmey Docklands (KAD), the franchise operator of the Docklands Light Railway (DLR), to replace the Traction Power SCADA System on the DLR.

With the impending procurement of new rolling stock and the long term enhancement and expansion plans for the network, the new solution will provide KAD and the DLR with a modern COTS based platform for their Traction Power Control.

The contract covers the complete design, engineering, build, installation and commissioning of a solution using SELLA CONTROLS’ Tracklink® SCADA product. Based on the latest Panorama E2 platform, the new system will be engineered to retain the functionality of the current system and to deliver an ease of migration for operators and minimise training activities.

The contract includes the supply of new Tracklink® SCADA server suites, main/remote operator and maintainer workstations plus the provision of a Network Management System for performance and fault analysis. Where practical, the system will also be enhanced to create ease of use for the operations team introducing asset specific user profiles to manage alarm conditions.

Chris Elliott, SELLA CONTROLS’ Business Development Manager for Rail commented. “The successful award of this contract is fantastic news for the business. This is a significant milestone for our Tracklink® product range. We are pleased that SELLA CONTROLS has been chosen by KAD to supply a modern COTS based solution for power control.”

Elliott added further. “With the impending expansion works planned by Transport for London for the DLR network, the implementation of this replacement solution will provide the necessary platform to KAD to enhance and expand its network of operations.”

Gavin Silvey, General Manager for KeolisAmey Docklands commented. “This is a high profile project for KAD and critical to the long term operations and resilience of the network. Selecting the right solution and delivery partner was critical and we look forward to working with SELLA CONTROLS on this project. We will adopt a ‘one team’ approach with my team from KAD but also our client DLRL and the team from SELLA CONTROLS.”

Raj Parmar, KAD Power Systems Manager added. “Where practical, the system will also be enhanced to create ease of use for our operational team introducing asset specific user profiles to manage alarm conditions.”

Once the new system has been delivered into operation SELLA CONTROLS will also continue to supply maintenance support services for the next five years.

SELLA CONTROLS wins a contract from ESG Rail for the provision of a device that physically prevents the over-speeding of trams

SELLA CONTROLS have been awarded a contract from ESG Rail, who has been contracted to develop, supply, install and commission a physical prevention of overspeeding (PPOS) device for the London tram fleet. This protection system will operate independently of the other tram monitoring systems and will stop a vehicle if it is found to be travelling at excessive speed within pre-defined locations.

Transport for London (TfL) began work on the feasibility of introducing this new safety measure, which has not been introduced on any UK trams before, shortly after the tragic overturning at Sandilands, Croydon, in November 2016. It is one of the recommendations set out by the Rail Accidents Investigation Branch (RAIB) following the tragic tram overturning and is expected to be fully operational by the end of 2019.

SELLA CONTROLS will provide the equipment necessary for the PPOS system to be installed on all of London’s trams. The system consists of a PPOS controller (EKE Trainnet) fitted to each tram, together with a Tracklink III Reader. Tracklink III beacons will initially be installed at a select number of high risk areas on the routes but will have the flexibility to be introduced elsewhere on the network.

In the event of a tram over speeding in a speed restricted area, the PPOS controller will interrupt the power to the PPOS safety relay. This will result in full service brake application and will bring that vehicle to a controlled stand-still.  This event will be alarmed at the London Tram control room via 3G/4G connection. SELLA CONTROLS will be providing the server and workstation for handling the alarms and storing the data. In addition SELLA CONTROLS are also responsible for providing a new Depot Wi-Fi system which will be used to download PPOS data from each tram as it enters the depot.

Mark Davis, TfL’s General Manager of London Trams, said: “We will never forget the tragedy at Sandilands and from day one have focused our attention on preventing this type of incident from ever happening again. Awarding the contract for a new automatic braking system Is a first for trams in the UK, and not only will it improve safety for customers in London, but we hope it will lead the way for other tram operators across the country. We will work hard this year to have the new system, which will automatically apply the brakes if a tram is exceeding the speed limit, in full operation by the end of this year.”

SELLA CONTROLS to supply a new PLC control system for Locomotives at British Steel’s Scunthorpe site

SELLA CONTROLS is pleased to announce that we have recently been awarded a contract by British Steel to design and supply a new PLC control system for the Hunslet Shunting Locomotives at its Scunthorpe site.

SELLA CONTROLS have a long association with these locomotives. In 1990 we supplied a fail-safe radio control system to RFS Engineering who had the contract to convert the locomotives to radio control operation. As part of this contract a Square-D SY/MAX PLC was installed for interfacing the radio control and manual controls to control the loco. Some 10 years later, in 2000, SELLA CONTROLS won a contract from British Steel to upgrade the radio control system and extensively re-program the Square-D PLC for new control functions.

The Square-D PLC has become impossible to maintain and repair as it has been obsolete for many years. As part of this contract SELLA CONTROLS will be replacing the Square-D PLC with a Siemens S7 PLC and will be providing new functionality including event recording.

The contract is for the supply, design and integration of the S7 PLC and wiring plus new software for the first loco. Providing it all goes well there will be further orders as British Steel slowly upgrades its other Hunslet locos.


Happy New Year

SELLA CONTROLS to deliver HS2 Enabling Works at Euston Station


Stockport, United Kingdom – Systems integration specialist SELLA CONTROLS is pleased to announce the contract award by Lowery Limited to supply its Tracklink® RTU products to support HS2 Enabling Works at Euston Station.

Lowery have been successfully delivering rail engineering projects since 1998 to Network Rail and the industry supply chain and are working closely with the main contractor for the works, Skanska.

With the impending construction of the new HS2 Terminus at Euston Station, existing equipment buildings need to be relocated to allow the clearing of the site to take place ahead of construction. As a result the existing Euston substation, used to feed the station power network, is to be relocated to a new substation building.

The contract covers the complete design, engineering, build, installation and commissioning of a Tracklink® RTU including its connection to the existing traction power SCADA system at Rugby ECR. Using the Network Rail accepted Tracklink® RTU solution, SELLA CONTROLS will be supplying a solution with a distributed architecture.

The new Euston SS RTU will be supplied with a master RTU controlling three slave remote modules installed in a number of substation buildings. In addition to this the RTU will have the ability to be controlled from either a local control panel or via an intelligent PLC delivering the auto reconfiguration of the power feeding arrangement in the event of a failure. These cabinets are interconnected via a fibre network providing diverse routing of control and indications for the substation.

Central to the Tracklink® RTU solution is a COTS based PLC supplied by Mitsubishi Electric. The Q Series PLC provides the RTU with its intelligence and control and consists of core processing (CPU), Communications and I/O Modules. The distributed architecture will use the Q Series CC-Link high speed network over the fibre to facilitate the connections between the cabinets.

Chris Elliott, SELLA CONTROLS’ Business Development Manager for Rail commented. “HS2 is the most prestigious rail project in the UK. The award of this contract by Lowery Limited is a great success for SELLA CONTROLS and we are proud to be part of these early stages of the project.”
