Railway Substation & Technical Building Construction

At Yapıtel, we deliver end-to-end solutions for the construction of railway substations and technical buildings. From design and construction to installation, testing, and commissioning, every phase is managed by our in-house engineering teams, ensuring full compliance with international standards.

Our expertise covers all infrastructure and superstructure works related to substations and surrounding areas, including steel structure design and assembly, installation and maintenance of power transformers, HV/LV switchgear equipment, and mechanical and electrical systems.

We also perform comprehensive technical analyses such as grounding calculations, short-circuit and harmonic analyses, surge arrester selection, insulation assessment, and RAM (Reliability, Availability, Maintainability) system evaluations.

Through CER power analyses and energy simulations, we ensure optimal system efficiency for both new line designs and line extension projects.

Our scope includes AC/DC power analyses, voltage drop assessments, energy consumption calculations, and regenerative braking evaluations, all verified according to international standards such as TSI, TSE, and AREMA.

Additionally, Yapıtel offers comprehensive engineering solutions for railway signaling, telecommunications, and control systems.
Our services include:

• Mainline signaling (Conventional, ETCS Level 1 & Level 2)
• Tramway and LRT control systems
• Level crossing systems
• Telecommunication infrastructures (SDH, MPLS, LAN, WLAN, GSM-R, DMR, TETRA Radio, etc.)
• Passenger Information (PIS) and Public Address (PAS) systems
• CCTV, SCADA, fire detection, alarm, and environmental monitoring systems
• Structural health monitoring and earthquake early detection systems

Through our multi-level maintenance and technical support services (L1, L2, L3), we ensure that all installed systems operate safely, efficiently, and continuously. Our integrated maintenance solutions cover all subsystems, including signaling, telecommunications, UPS, point heating, wheel detectors, HVAC, security, and information systems — guaranteeing reliability and operational excellence across every project.
