Intercity & Commuter Rail

Reinforcing regional connectivity through modern railway systems

We’ve contributed to hundreds of kilometers of intercity and suburban rail infrastructure

Intercity and commuter rail systems are essential to regional cohesion and urban mobility. They enable fast, safe and sustainable travel between metropolitan areas and surrounding territories. At Sener, we bring over 30 years of experience in the design, modernization and integration of regional and suburban railway infrastructure. Our multidisciplinary teams deliver high-value solutions that enhance service capacity, operational safety and energy efficiency — whether for new corridors or upgrades to existing lines.

From urban integration of regional trains in Spanish cities like Barcelona and Valencia to commuter rail frameworks in Mexico, Poland and India, our teams have addressed the full range of design and operations challenges — including infrastructure layout, station modernization, energy systems and passenger flow optimization.

Specialists in upgrading legacy lines and shared corridors

Our experts combine civil engineering, transport systems and architecture to address the particular demands of commuter and intercity services: integration with dense urban areas, safe operations in shared corridors and infrastructure adapted to mixed rolling stock.

Why choose us

We specialize in modernizing legacy rail lines to meet current and future demand, applying RAMS methodologies, station simulation tools and signaling optimization to reduce travel times, increase frequency and enhance user experience — all with minimal impact on operations during construction.

How we work

Our approach is both systemic and local. We tailor each project to the specific characteristics of the territory, traffic and infrastructure, combining simulation, stakeholder engagement and advanced engineering. We design lines that support intermodal integration, rolling stock transition and phased implementation, with special attention to cost-effectiveness and energy optimization.

We provide comprehensive engineering services across all project phases: from feasibility studies and profitability analyses to infrastructure design, modernization and construction management.

From planning to operation with seamless integration

We support public and private operators throughout the entire project lifecycle. Our teams ensure smooth commissioning, optimized train paths, integrated stations and aligned communications and control systems — enabling seamless intercity and commuter rail operation from day one.

Intercity and commuter rail expertise worldwide

Our capabilities cover track alignment, tunnels, bridges, station planning, electrification, signaling, rolling stock integration and safety audits. We also apply BIM, simulation and energy optimization tools to maximize efficiency and resilience. This combination allows us to deliver modern rail networks that strengthen regional mobility and improve quality of life.
