Multi-Purpose Train Maintenance Depot
FS Engineering contributed to the construction of the Naples Multi-Purpose Train Maintenance Depot (IDP), a modern train maintenance facility dedicated to the entire High-Speed train fleet and regional transport rolling stock.
The facility was phased in across the following steps. In 2002, the arrival and departure sidings entered service, consisting of six covered and six open-air tracks for routine train maintenance and cleaning operations. Later on, the Computer-Based Interlocking (CBI/ACC) system was commissioned to regulate traffic movements between Naples Central Station and the depot. The compliance certificates for this interlocking system was issued by a technical board composed entirely of company experts.
The third phase involved the commissioning of a distributed-logic safety system, in view of the final expansion of the facility via a concentrated-logic CBI. In 2008, the entire CBI system was brought into active service alongside the completion of the lineside mechanical systems, marking the full operational capability of the IDP facility.
Heavy Maintenance Workshop
FS Engineering oversaw the construction drawings and detailed design and the execution of upgrade works at the Vicenza Heavy Maintenance Workshop (OMC), a facility dedicated to high-speed train maintenance.
The facility, originally built in the early 1900s and improved over the years, spans an area of approximately 140,000 m² in the industrial district of the city, occupying a strategic position adjacent to the Milan–Venice rail corridor. The expansion of the high-speed fleet has progressively consolidated the facility's role as a leading hub for servicing new trainsets, particularly the ETR 500 and ETR 1000.
The redevelopment and modernisation of the facility have successfully introduced new capabilities and advanced operational standards, adapting the infrastructure to meet the maintenance requirements of next-generation trains.
Routine Maintenance Depot
FS Engineering oversaw the construction drawings and construction work for the new Turin Routine Maintenance Depot (IMC), a facility aimed at reorganising the track layout and constructing modern buildings to efficiently and sustainably centralise all maintenance operations.
The new depot carries out maintenance work on both regional and high-speed trainsets with maximum operational efficiency and compliance with environmental regulations. The area covered by the works spans approximately 270,000 m² within a wider 340,000 m² rail yard where Trenitalia conducts its maintenance activities.
The project is integrated into an urban context undergoing major regeneration schemes promoted by the local authority, which include the construction of sports facilities, as well as retail, residential, and business developments. Overall, the intervention aims to provide a unified design for the new depot, seamlessly integrating the new architecture, the rail infrastructure, and the existing structures in line with Turin's development expectations.
Routine Maintenance Depot
FS Engineering oversaw the construction drawings and construction supervision of the new MAV3 maintenance shed dedicated to ETR 1000 trainsets at the new Milan Routine Maintenance Depot (IMC). The scheme also included upgrading the access track throats on both the Milano Centrale and Milano Greco Pirelli sides, as well as reorganising the internal layout with the construction of service roads, paved areas, and car parks.
The new maintenance shed has internal dimensions of approximately 340 x 25 m, with an average net height of 9 m. The structure was built predominantly using precast reinforced concrete elements, while three internal tracks are laid over precast inspection pits.
Ancillary services accommodations, housing offices and staff changing rooms, were built adjacent to the main building; this two-storey structure measures approximately 100 m in length and 7 m in width.
The facades of the building are finished with composite panels and corrugated sheet metal, with the longitudinal elevations featuring a tricolour band that defines the facility's brand identity. Finally, the new maintenance shed is equipped with specialized systems designed for the servicing of next-generation rolling stock.
Routine Maintenance Depot
FS Engineering oversaw the construction of new facilities and the upgrading of existing buildings at the Bologna Routine Maintenance Depot (IMC), including all necessary building systems, as well as interventions on the tracks, overhead line equipment, and signalling systems.
The improvement of this new facility represents the company’s first construction drawings for a maintenance depot developed entirely using BIM methodology. This enables the client to reuse the digital models for subsequent building operations and maintenance activities, driving innovation and lifecycle optimization for the facility.
New, modern Trenitalia executive offices
FS Engineering managed the execution of works and procurement for the conversion of several industrial buildings into offices and operational facilities connected to railway activities in the Firenze Romito area.
The project is part of the wider remodelling of the Florence Rail Hub. Following the commissioning of the Osmannoro Pole, large building volumes became available in the former Romito locomotive depot due to the decommissioning of legacy maintenance operations. The restoration of the former Firenze Romito engine workshops stands as the company’s first construction drawings for a single building developed using BIM methodology, allowing the client to utilize the digital models for future building operations and maintenance activities.
