CEMOSA is a Founding Member of the European iniciative “Europe’s Rail  Joint Undertaking” through the ‘European Smart Green Rail Joint Venture’ (eSGR JV) consortium, led by CEMOSA. CEMOSA was already an Associated Member of Shitt2Rail JU (predecessor of Europe's Rail). CEMOSA's participation in these European initiatives is the result of the company's strategic CEMOSA’s participation in these European initiatives is the outcome of the strategic commitment of the company with Research and Innovation activities in the field of railway infrastructures. Being a member of Europe's Rail Joint Undertaking ensures CEMOSA’s enrolment in international research projects dealing with railway infrastructures as far as 2027 and consolidates the company long term strategic railway research agenda. In the Europe's Rail initiative, CEMOSA is involved in 2 projects (IAM4RAIL and RAIL4EARTH).
In the project “IAM4RAIL Holistic and Integrated Asset Management for Europe’s RAIL System”, works on the implementation and demonstration of intelligent maintenance tools for civil engineering asset management. On the other hand, in the project “RAIL4EARTH Europe’s Rail Flagship Project 4 - Sustainable and green rail systems” CEMOSA works on the implementation and demonstration of energy digital twins of railway stations (lighting, HVAC and scheduling) and flexibility mechanisms to create energy hubs for future energy markets.
Within the Shift2Rail Initiative, CEMOSA takes part in five projects. In “Research into enhanced tracks, switches and structures” (IN2TRACK, IN2TRACK2 and IN2TRACK3), CEMOSA develops models and design tools for the validation of the new components in the track and the development of dynamic behaviour models for bridges in order to analyse the performance of the structure. CEMOSA also develops new environmentally sustainable support layers for ballastless tracks, underwater auscultation equipment for bridge pile inspections and structural analysis under a probabilistic approach. Moreover, CEMOSA participates in IN2SMART e IN2SMART2: “Intelligent Innovative Smart Maintenance of Assets by integrated Technologies”, where they collaborate in the design of advanced algorithms for the detection of failure and the assessment of degradation in railway components using data analytics techniques. CEMOSA also developed and designed a general framework for decision support tools in railway maintenance and intervention actions planning.
Moreover, CEMOSA participated as a partner in the H2020 "FORESEE: Future proofing strategies for resilient transport networks against extreme events" project where they developed novel methodologies using data analytics techniques for the adoption of sustainable drainage systems in linear infrastructures. CEMOSA also worked in the development of a procedure for seismic analysis and micro-zoning in structures. On the other hand, CEMOSA led the development of resilience plans, where they developed methodologies for the evaluation of the resilience of transport infrastructures and the identification of opportunities to improve it.
CEMOSA coordinates the "OMICRON: Towards a more automated and optimised maintenance, renewal and upgrade of roads by means of robotised technologies and intelligent decision support tools" H2020 project. This project develops an Intelligent Road Asset Management Platform. The development of the Digital Twin and the intelligent maintenance platform are transferable to the railway sector.
Co-financed within Europe's Rail Joint Undertaking in Horizon Europe, CEMOSA participates in the research project "FP3-IAM4RAIL: Holistic and Integrated Asset Management for Europe's RAIL System", coordinated by Adif. CEMOSA is working on the implementation and demonstration of tools for the intelligent maintenance of railway infrastructures. More specifically, CEMOSA works on the integration of data from diverse sources, including historical data, satellite information, geotechnical information and information from IoT sensors. This structure allows the development of algorithms for predictive maintenance using Artificial Intelligence and addressing both bridges and earthworks. CEMOSA aims to develop a Digital Twin oriented management platform for bridges and earthworks.

At a national level, CEMOSA coordinated the “ROBOTRACK: Automation of installation systems for a new concept of low-weight slab track” project, co-funded by the RETOS-COLABORACION programme (Government of Spain). In this project, CEMOSA participated in the design of supporting layers based on recycled materials, the reliability and costs (RAMS&LCC) analysis of the new slab track solution and in the definition of the construction methods. CEMOSA also participates in the "RESILTRACK: Resilience of railway infrastructures to Climate Change" project of CDTI's CIEN programme in which hybrid algorithms are designed for the analysis of the structural health of railway viaducts, their implementation and integration into the BIM environment.
In addition, CEMOSA coordinates the "TECH4INFRA: New technologies applied to the efficient and safe management of civil infrastructures" project, co-financed by the IDEA Agency of the Andalusian Regional Government. CEMOSA, apart from the coordination of the project and the demonstrators and definition of the technical requirements, is in charge of the integration of the inspection and monitoring information of the project. In this sense, CEMOSA develops an asset management platform oriented to a BIM-GIS environment, including the various sources of information developed in the project such as inspection drones and Edge Computing monitoring systems.

Innovations in other fields:
In the Energy and Buildings research area, CEMOSA coordinates two projects: the eTeacher H2020 project on promoting and changing the behaviour of energy users in buildings and the ebalance-plus H2020 project on increasing the energy flexibility of distribution grids. Moreover, CEMOSA is carrying out the AICREDITS (funded by CDTI), whose objective is the use of Artificial Intelligence (AI) technologies to improve energy audits. co-financed by the CDTI.
In roads, CEMOSA participates in “REPARA 2.0: Advanced and sustainable developments for efficient road pavement rehabilitation techniques” research project, funded by the CIEN programme (Government of Spain). Within this project, CEMOSA designed new cold asphalt pavements with 100% of RAP, further developed the high performance pavement auscultation system patented by CEMOSA in a former project, and developed a software tool for the calculation of asphalt pavements taking in to account the new materials and construction methods developed within this project.
Transversal to all areas, CEMOSA participates in the "SARIL: Sustainability and Resilience for Infrastructure and Logistic networks" project, financed by the Horizon Europe programme. The project develops tools for the evaluation and improvement of the resilience and sustainability of logistics networks, using business intelligence and data analysis tools among others.
