Railway

Applus+ rail engineering, consultancy, and inspection services apply to conventional and high-speed railways. We deal with complex railway projects, most of them with long tunnels in harsh geological conditions and major structures with different typologies. We also have experience in metro projects and the development of Spain's HSR (High-Speed Rail) network, providing services in all the corridors.

Railway inspection
We provide services for design review, QA/QC, quantity surveying, schedule monitoring, budgetary control, contract management, and expropriations. Our portfolio includes complete services: platform, track, electrification, safety, and communication facilities.

Railway geotechnical engineering
At Applus+, we specialize in geotechnical engineering, and our multidisciplinary team of engineers and geologists has extensive experience. Our decades-old knowledge, combined with our geotechnical equipment and laboratories, allows us to offer our clients comprehensive solutions to the most complex problems. We have the latest technology in drilling machinery and equipment for geophysical work.

Railway risk management | Geotechnical instrumentation and monitoring
Applus+ continually explores the practical application of advanced technologies to provide innovative, cost-effective, and appropriate solutions to ensure risk management in the railway industry through geotechnical instrumentation and monitoring works and technologies. 

We have worked on the instrumentation and monitoring of several metro projects, such as Line 9 in Barcelona and the Riyadh and Lima Metro projects, among other works developed in different kinds of line infrastructure, HSR, and Roads.

Bridges instrumentation and monitoring
At Applus+, in collaboration with Calsens, we are experts in the intelligent monitoring of structures using our optical fiber technology. Our multidisciplinary team includes experts in different areas of knowledge, including civil engineering, telecommunications, and structural engineering. We are a world reference in structure testing and monitoring, with many published works and patents.

Pre- and post-dilapidation survey
Applus+ has accomplished important goals in providing dilapidation services. We have been involved in significant projects worldwide, such as the Metro networks in Barcelona, Doha, and Riyadh. For the latter, we did the dilapidation survey for all the lines and accomplished the inspection of more than 1,000 buildings within four months.

Our team of highly skilled engineers, combined with our leading technology (SICE), has allowed us to achieve the best performance in this kind of project.

Laboratory testing
We perform material tests and operational tests, both in laboratories and on-site, to satisfy the needs of developers, builders, public institutions, and engineering or architecture companies, which need to verify proper execution of the works regarding the quality of the materials used and their correct placement and operational performance. 

Quality control must be considered from the start of the railway construction process to identify and control the materials and the most critical units.

We have been involved in the development of the HSR in Spain, providing railway support services for all the new corridors. Currently, several laboratories are working on the Northwest HSR line in Spain. 

Applus+ provides comprehensive rail engineering and railroad consulting services across all stages of the railway lifecycle — from design and construction to maintenance.
