During 2020 SELLA CONTROLS has been able to progress the Tracklink® product suite across many projects. These have included solutions for Network Rail, Transport for London and Docklands Light Rail. Some of these projects have resulted in major product developments and also industry milestones for the business. The headlines are as follows:

Tracklink® SCADA deployed to Docklands Light Rail. During the last 12 months SELLA CONTROLS has been in the process of replacing the existing Siemens Rail Com Solution at Docklands with a new Tracklink® SCADA system. The new solution features a quad server architecture, geographically based in two locations (Poplar and Beckton Control Rooms), interconnected via a diverse A & B communications network. This diverse network consists of an OTN based solution (Line A) and CISCO Networks Solution (Line B).

The servers connect to circa 50+ Siemens Fastflex RTU installed across the network. These are providing DLR with the control of AC/DC Substations, Station Telecommunication Assets and Tunnel Ventilation Control (SIL Certified implementations) at Bank Portal and on the Lewisham and Woolwich Arsenal river crossings.

The staged expansion of the DLR network over many years since the first Cromos System went live on the Lewisham Extension, saw functionality introduced. As a result, the MT700 Protocol has been adapted several times. As part of the Tracklink® SCADA rollout, we have implemented 4x different MT700 versions into Panorama E2 to allow us to interface to the different Fastlfex RTU builds. This includes 3x different processor types (FF014, FF014e and FF015e).

As part of the FAT process we completed a 100% I/O check in parallel with DLR’s existing reference model and also completed on site pre commissioning with individual RTU and entire sub systems to confirm a working solution. Running parallel to this has been User Acceptance. The system is now in over & back migration testing with the ‘Go Live’ date scheduled for later this month.

Tracklink® RTU achieves latest product acceptance. Following the completion of the trial installation at Euston, the Tracklink® RTU has now achieved acceptance from Network Rail for use with DNP3 Serial. This was completed using a Tracklink® RTU connected to the FoxSCADA System at Rugby. The RTU has now been in operation since December 2019. The solution featured a distributed architecture consisting of a Master RTU with three remote I/O panels providing control of power on the Euston site. With the TPCMS trial site deployment now scheduled at Feltham Depot, Tracklink® RTU product acceptance continues to achieve its product development milestones.

Tracklink® P2P achieved full acceptance for both AC and DC networks last year. Its deployment across all routes has been extensive and supplied either directly or via E&P contractors and Network Rail delivery teams. New product developments are in place and ready to be launched later this year. Watch this space for future up dates.

SELLA CONTROLS is pleased to announce an Instrumentation System contract award from Reaction Engines to facilitate engine test comparisons and analysis for their revolutionary SABRE engine

The Instrumentation System contract awarded to SELLA CONTROLS consists of several key architectural elements consisting of SCADA, Data Acquisition, High Speed Data Acquisition and Historian systems to facilitate engine test comparison and analysis for performance tuning. SELLA CONTROLS were successful despite strong competition from rival system integrators, leveraging on our skills, capabilities and technical expertise.

The package scope includes for the design, engineering, panel build, testing, commissioning and support for engine testing at site for each engine build. The first build facilitates a modular test of primary major mechanical components, with build 2 concluding the engine construction with the balance of mechanical plant and testing as a complete unit.

The application for the Instrumentation System is to provide the monitoring, visualization and data logging of sensor values for the SABRE engine, an innovative propulsion technology under development and test by Reaction Engines. The engine will be capable of operating from a standing start, to reach Mach 5 speeds (five times the speed of sound) and then transition to rocket mode for space access attaining Mach 25. This will enable a new generation of air and space vehicles providing efficient long range hypersonic air flight plus re-usable responsive space launch.

SELLA CONTROLS Complete Remote Factory Acceptance Test

The current COVID-19 restrictions on travel and social distancing means that traditional client attended Factory Acceptance Tests are not possible for all projects at this time.

However, this presents the perfect opportunity to use technology to develop new methods for these activities. These pictures show us performing a remote FAT for a solid state SIS logic solver.

Using a combination of fixed and mobile cameras, coupled with clear procedures and detailed test cases, we were able to take the client through the functionality of the system and allow them to inspect the panel build.

Coronavirus COVID-19: Statement – SELLA CONTROLS LTD

With the rapidly developing situation regarding Coronavirus COVID-19 we are letting you know what steps SELLA CONTROLS is undertaking to ensure we are able to continue to operate and meet our customer’s needs whilst also ensuring the safety of our employees.

Underlying all of our actions is a recognition of the importance of the health and safety of our employees, our customers, and their respective families during these times of uncertainty. Our business is the supply and maintenance of mission and safety critical systems for high hazard industries and critical infrastructure; in many cases our customers’ activities and products are essential for the wider community and we will strive to continue to support our customers through this crisis.

We would also like to reassure all our technical support/maintenance contract holders that our aim is to continue to provide the necessary support levels.

We constantly monitor and follow UK Government advice and our current position is that all employees who can work from home will be encouraged to do so and we have put in place the technology and infrastructure in order to facilitate this. We have ceased all non-essential travel and are encouraging both employees and clients to use technology to communicate; such as conference calls and video conferencing rather than face-to-face meetings.

We currently plan to maintain core operations at each of our offices in Stockport, Ashby de la Zouch and Coalville to enable us to continue to undertake critical roles in safety systems, operations, testing and production and thereby provide the support for our customers when they are likely to need us most. We have in conjunction with this brought in new working practices to minimise the risk to health; such as enhanced cleaning and hygiene protocols and the minimising of group working and reducing the risk of unnecessary contact and we would ask that any visitors also adhere to these policies.

Our staff are regularly briefed on developments and we continue to monitor closely the evolving situation and adopt suitable approaches to work in line with advice from the UK Government and the World Health Organisation.

First business lands in Apollo Court

Firm expands operation in county – Article by Leicestershire County Council

SELLA CONTROLS Ltd is set to create new jobs after becoming the first business to set up shop at a new £5.5m industrial park in Coalville.

Apollo Court Business Park was developed to boost business in the town by supporting start-ups and firms looking to expand.

We invested in Apollo Court as part of our corporate asset investment fund, which aims to boost the local economy and generate income for frontline services.

SELLA CONTROLS, which specialises in developing functional safety systems for a range of industries – including the rail industry, is taking advantage of this approach and expanding its operations in Coalville.

The firm, which works with companies such as Network Rail, Transport for London and Bombardier, has offices in Ashby and Stockport.

Ian Wright, Chairman of SELLA CONTROLS, said that the unit at Apollo Court was in an ‘ideal location’.

He said: “We needed to explore looking for industrial space as our equipment such as PPE and materials was taking up space in our Ashby offices.

“The unit in Coalville was ideal as it is close to our offices, based in the East Midlands and has accessible links to London. It is a blank canvas, fit for us to use however we want.

“It was important for our development to get this unit. Our business is growing, and this expansion means we have new vacancies available.”

One of the firm’s designs is a unique system that ensures that automatic doors on trains open at the right time and place when stopping at a station.

Ian said: “There are currently new trains being built that will be coming into service. However, trains are getting longer and longer, but platform lengths stay the same.

“We have developed a beacon that goes onto the rail track so when a train passes over it, it gives off a signal which states which doors open upon arrival and more importantly, which ones stay closed.

“We’re the only company in the country that does this.”

However, Ian and his colleagues, who took over the company in 2007, do not plan to stop expanding the business in Leicestershire or even the United Kingdom.

He said: “The company has been going for 46 years and my business partners and I have spent 13 years developing the rail side.

“I’m proud we have built a workforce of 110 people and have sustained relationships with big companies.

“We’ll now be looking to expand our systems in Europe.”

A range of high-spec industrial units ranging from 1,000 to 9,000 sq. ft. (92-836 sq. m.) are still available at Apollo Court.


I’m delighted to see the first business move into Apollo Court.

“Supporting businesses is important; it helps boost our local economy and creates jobs.

“SELLA CONTROLS staying within Leicestershire proves how attractive the county is as a place to not only work, but live, invest and socialise. We have been very pleased with the level of occupier interest in the units and hope to make some more announcements soon.”

Person: Councillor Byron Rhodes, county council deputy leader


The venture is part-funded by a £2.4m grant from the Local Growth Fund, a pot of government funding awarded to the Leicester and Leicestershire Enterprise Partnership Limited (LLEP) for projects that benefit the local area and economy.

Kevin Harris, chair of the LLEP, said: “Our Local Growth Fund was set up to benefit the wider economy of Leicester and Leicestershire. SELLA CONTROLS’ move to the Apollo Court Business Park in Coalville is the culmination of a project that will see jobs created and revenue generated in the local area.

“I’m proud that the LLEP was able to support this project, and deliver a top-class site for businesses to move to and thrive now and in the future.”

Premier Rail Specialists to continue Partnership to Support Transport for London Systems

Systems integration specialist SELLA CONTROLS and telecommunications business telent Technology Services Ltd are to continue their partnership in providing maintenance and support services to Transport for London (TfL).

Following the successful award by Transport for London of the ‘1FM Service Agreement’ to telent, SELLA CONTROLS has been awarded a 7 year third line support agreement for the systems it supplied to the Central and Piccadilly Line Control Rooms.

The ‘1FM Service Agreement’ combines mission-critical maintenance services, system design and upgrade works for TfL’s technology assets across varied environments including roads, rivers, the London Underground and office buildings. SELLA CONTROLS has been working closely with telent over the last two years in providing support for the systems within an existing contract. During this time the two companies have built a strong partnership supporting the Central Line and Piccadilly Line Systems. A partnership that will now continue into the new agreement.

SELLA CONTROLS built and commissioned the Central Line CCS and Piccadilly Line RCS solutions, using its integrated Tracklink® SCADA application for telecommunications. This included the integration of CCTV, Telephony, LLPA, SCADA and the safe control of ETCDS. These systems are critical to the operation of the two lines, requiring 24/7 availability.

telent Technology Services Ltd’s maintenance service team, based in East London, will carry out all first line maintenance activities on the systems with SELLA CONTROLS providing third line support. In addition to operational support, annual Planned Preventative Maintenance services on the key systems will be completed by SELLA CONTROLS.

Chris Elliott, SELLA CONTROLS’ Business Development Manager for Rail commented; “the Central Line CCS and Piccadilly Line RCS solutions have now been operational for some time during which the two companies have provided a high quality of maintenance services ensuring that both systems achieve optimum performance. We are looking forward to the continued working relationship with the maintenance team from telent building a strong partnership over the next 7 years. This is a great example of the supply chain working collaboratively in the best interest of the customer.”

Ben Armstrong, Account Director at telent Technology Services Ltd added; “SELLA CONTROLS have supplied excellent third line support for the operationally critical control room systems installed on the Central and Piccadilly Lines over the past 2 years. With this new contract award we will continue to provide an outstanding service to TfL assisting them to keep London moving.”

The support agreement between telent and SELLA CONTROLS commenced on 1st January 2020 when the current Communications Maintenance Services contract expired.
