Overhaul of the CHIAIA-NAPOLI Funicular
The twentieth year overhaul and modernization of the Chiaia Funicular was successfully completed in January 2025, following an extensive program of structural and safety upgrades. The intervention included non-destructive testing (NDT) in accordance with UNI EN ISO 9712:2022 standards, along with the inspection and restoration of vehicles, rope checks, issuance of static certifications, fire safety inspections, track recalibration, and updates to the grounding and lightning protection systems.
Renovation works were also carried out at the stations, involving machine rooms, maintenance pits, railings, signage, staff facilities, and passenger information systems. The funicular infrastructure underwent a complete modernization, including the full replacement of bullwheels, sheaves, tracks, and drive systems, to support increased passenger capacity and meet the requirements of NTC 2018 standards. New electrical and mechanical systems were installed, such as UPS units, motors, brakes, hydraulic units, video surveillance, intercom, and sound distribution systems. The control system was upgraded to a digital, automated platform with remote monitoring and enhanced emergency management functions. The vehicles underwent major refurbishment, including the replacement of pantographs, overhaul of braking systems, renewal of wheels and suspensions, installation of new maintenance hatches, and integration of high-durability door-opening mechanisms. To ensure safety during construction, certified fall protection systems, modular fences, temporary walkways, and fire safety equipment were installed. The project was finalized with the delivery of the executive design, required certifications, and complete “as-built” technical documentation, ensuring a significant improvement in the reliability, efficiency, and safety of this critical public transport system in Naples.
