Advantages of rail technology

Standard-compliant & railway-compatible

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

Modular & functional

User-oriented cabins, modules and technical cells - can be used individually or in combination, always with a focus on user-friendliness

Quick to use & ready to install

Pre-assembled units including HVAC, electrics and routing - with tested system integration.

Robust & durable

Paintwork to C5M, fire protection REI 30-120, vibration and weather resistant - tested for rail and tunnel vehicles

Everything from a single source

Our engineering teams plan the mechanics, HVAC, electrics and routing as a complete system - with 3D CAD, FEM calculation, shock/vibration simulation and EMC-compliant design for rail use.

Planning & design

We analyze technical requirements, clarify standard specifications and develop a viable overall concept - in accordance with railroad standards and operator requirements.

Construction & Engineering

Our engineering teams plan mechanics, HVAC, electrics and routing as a complete system - with 3D CAD, FEM calculation, shock/vibration simulation and EMC-compliant design for rail use.

Steel & cabin production

From the load-bearing frame to the functional unit: we manufacture all structural elements in our own factory - welded in accordance with EN 15085 & ISO 3834, tested for dimensional accuracy, load-bearing capacity and suitability for use on railroads.

Surface protection & fire protection

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

Electrical engineering & HVAC integration

From the control cabinet to the air conditioning system: we integrate all systems in-house - coordinated, pre-wired, EMC-compliant and FAT-tested. Also for redundant HVAC, PLC controls and safety-related applications.

Factory test & acceptance

Every cabin or rail unit is comprehensively tested in the factory - mechanically, electrically and climatically. Our FAT protocols document functional safety, integration and standard-compliant design.

Loading & Logistics

We take care of loading, transport coordination and, if required, accompany the final assembly - be it at the vehicle manufacturer, system integrator or end customer. Gföllner delivers - ready for operation, worldwide.
