Sirail Services : a highly qualified team for your projects, wherever they are.

Sirail Services can provide you with fully qualified teams for electrical and electromechanical activities (repairs, retrofits, installations, etc.) within a very short timeframe. The wide-ranging skills of our technicians enable us to provide all related services in specialized environments, such as workshop dismantling, piping, mechanical and welding services. Our teams work autonomously and reliably on all complex projects.

Safety First

Our teams, due to their mobility, are accustomed to working in ever-changing environments and are thus exposed to different risks depending on the site or industrial sector they are intervening in. Moreover, we understand that an accident on your site is both our accident and your accident. That’s why we strictly adhere to current regulations and your site’s safety instructions. We ensure that technicians on a mission have all necessary certifications and training. Our team leaders are made aware and have the responsibility of safety reminders to minimize accident risks as much as possible.

Diagnosis and repair of electrical systems

Analyzing malfunctions of complex electrical and electromechanical systems requires sharp technical skills. Our experienced technicians travel to your site to perform a precise diagnosis of the repairs, then develop a detailed plan of the operations to be performed. When necessary, our engineering office or our method service is mobilized to provide you with complete support, including the supply of electrical and electromechanical assemblies ready to be installed (harnesses, cable networks, boxes, and electrical cabinets..), or components to be replaced.

Dismantling of electrical workshop

Reorganizing the space of your production site should not be improvised, especially when it involves production tools related to the electrical field. The expanded skills of our Sirail Services technicians allow us to undertake these very specific missions, such as workshop dismantling, performed with professional artistry, within the strict framework of current safety standards, and on your site.

Upgrading electrical systems

Whether it’s an upgrade of onboard electrical cabinets or not, chests or integrated modules or not, of complex wiring networks (HV MV or LV) installed, the configuration update campaigns on these electrical and electromechanical systems must be completed within a non-negotiable timeframe. Sirail Services prepares these interventions in advance by deploying the methodology adapted to the access conditions of the products to meet the mission’s constraints while ensuring compliance with quality requirements.

Quality and compliance

Supply and installation of electrical and electromechanical assemblies

Use case

Dismantling a dielectric test line

Railway Production line relocation

Dismantling a production hall is not improvised. Sirail Services was there to help our client modify and optimize the organization of production spaces.

To prepare for such a mission, our teams conduct rigorous identification and an in-depth analysis of the elements to be dismantled, the nature of the electrical (for example, dielectric test lines) and mechanical production equipment to be dismantled and moved. The teams thus have a precise plan of tasks and reinstall the equipment in the spaces defined in advance (production or storage area).

These interventions are very sensitive in terms of deadlines and quality. Missions can be carried out at night or over the weekend to not disrupt production. In any case, Sirail Service listens to our clients to provide them with tailor-made solutions and meet their needs.

Maintenance : 200 RER trains

Railway Maintenance

The wide-ranging skills of Sirail Services technicians enable them to work on various types of retrofit, maintenance or rolling stock renovation projects, directly on the operators’ technical sites.

For more than 2 years, Sirail Services has been working with our partner SNCF on level 3 and 4 maintenance services in collaboration with our customer’s teams of technicians. The mission consists of improving the reliability of rolling stock, and the Sirail Services team works on all electrical equipment and systems (cereca, telediag), mechanical systems (brakes), and on the replacement of parts such as windscreens and signalling lights.

The maintenance and retrofit activities concern a fleet of 200 trains on the RER network, and were carried out over a period of more than 2 years.

As trains are running during this major maintenance campaign, it is essential that workshop schedules are respected: the slightest delay would have consequences for all regional traffic, on one of the most important lines in terms of passenger numbers.

Sirail Services has met its commitments to the utmost satisfaction of our customer and partner, who is concerned about passenger comfort and safety.
