Advantages of railway technology

Compliant with Standards & Suitable for Rail Use

Design and manufacturing in accordance with EN 15085, EN 50125, EN 45545, and project-specific guidelines

Modular & Functional

User-oriented cabins, modules, and technical units—usable individually or in combination, always with a focus on ease of use

Quick to set up & ready to install

Pre-assembled units, including HVAC, electrical systems, and routing—with verified system integration

Sturdy & Durable

Paint finish in accordance with C5M, REI 30–120 fire protection, vibration- and weather-resistant—tested for rail and tunnel vehicles

Everything from a single source

From the first sketch to final commissioning, we support your project with experience, technical precision, and a sense of responsibility

Planning & Design

We analyze technical requirements, clarify standard specifications, and use this information to develop a viable overall concept—in accordance with railway standards and operator requirements.

Design & Engineering

Our engineering teams design mechanical, HVAC, electrical, and route layout systems as an integrated whole—using 3D CAD, FEM analysis, shock/vibration simulation, and EMC-compliant design for railway applications.

Steel & Cabin Manufacturing

From the load-bearing frame to the functional unit: We manufacture all structural components in our own plant—welded in accordance with EN 15085 and ISO 3834, and tested for dimensional accuracy, load-bearing capacity, and suitability for railway use.

Surface Protection & Fire Protection

Our modules meet fire protection requirements in accordance with EN 45545, REI 30–120. High-quality coatings (C3–C5M), hot-dip galvanizing, and, upon request, EX/EMC versions ensure reliable operation even under extreme environmental conditions.

Electrical Engineering & HVAC Integration

From the control cabinet to the air conditioning system: We integrate all systems in the building—coordinated, pre-wired, EMC-compliant, and FAT-tested. This also applies to redundant HVAC systems, PLC controls, and safety-critical applications.

Factory Inspection & Acceptance

Every cabin or train unit undergoes comprehensive testing at the factory—mechanical, electrical, and environmental. Our FAT reports document functional safety, integration, and compliance with standards.

Loading & Logistics

We handle loading, coordinate transportation, and, upon request, assist with final assembly—whether at the vehicle manufacturer, system integrator, or end customer. Gföllner delivers—ready for operation, worldwide.
