Railway signalling, development of our structured engineering offer
Our teams are working to expand a model focused on expertise and sustainability.
Security has always been at the heart of our clients’ concerns, in multiple areas, including nuclear and healthcare.
Our clients’ challenges contribute to the structuring of our businesses so that we can respond to their projects in a relevant way. After several years of contributing our expertise to railway projects, we are now creating a structured offer that reflects our skills and our positioning in this sector. We aim to become a major player in railway signaling design in the long term, offering quality services through a team of experts for clients of varied railway networks.
Railway signaling is a set of equipment, devices, and regulations designed to ensure the safety of railway traffic and therefore of passengers. It is a so-called “intrinsically safe” profession. It is generally operated by “zone”, generally delimited by a post with a control/command organ, managing one or more stations and “blocks” which are the junction between the stations and the posts. The complexity lies in the fact that each network, each country has several technologies, sometimes relay, electromechanical or mechanical and increasingly often computer-based.
Railway signaling is also, exponentially, taking into account the challenges of fluidity and train frequency by managing increasingly reduced spacing and increasingly high speeds. Thus, the challenge is to mix technical data with data dedicated to passenger information, ticketing, etc.
Our teams are working to develop a comprehensive and sustainable railway signaling offering that meets the needs of our clients and the evolving challenges of the railway sector. We are confident that our expertise and experience will allow us to become a key player in this growing market.
Our offer is positioned on the complete cycle of railway signaling studies.
In the first place, our teams work on the so-called “emergences”, upstream or “general” studies which include the following studies:
- Operations, they define the needs of the project owner in terms of train frequency, flow rates, flows, etc.
- Initializations, which define a summary and forecast budget envelope as well as a forecast calendar and a first technical draft
- Preliminaries, which are the studies including the operation program, the socio-economic file, the technical and environmental notice, the administrative procedures file
- Programs or functional analyses, this is the first and most technical approach, the program defines the equipment to be implemented according to the movement of the trains, all transcribed into a summary signaling diagram
- Functional specifications involve the development of general and specific operating principles via single-line diagrams. They also describe all the equipment used
- Preliminary project (AVP), the aim being to carry out an initial budgetary approach, called forecast, corroborated with a signaling diagram and a descriptive note of the system to be implemented and its equipment
Also, our experts carry out so-called “detailed” studies
which include studies:
- PRO (Project), they define more precisely the budgetary estimate of the project, the technical plans (functional specifications of circulations transcribed in the form of tables), descriptive notices, it is the study of input data for execution studies
- And the DEX studies (executions) which are the transcription of the technical plans into detailed diagrams and which will serve as cabling plans for the field
Our teams are operational and support you to analyze, think, innovate, create and make your projects a success.
