INTRODUCTION Studio Macetti Macetti engineering firm provides engineering services in the field of metro, tram and railway superstructure systems. The range of activities provided covers technical designing, executive managing, operating on-site engineering. Our technicians ten-year experience and the continuous updating to the ever-changing market, enable our team to develop the best solutions both technically and financially. Studio Macetti can provide an effective support to Main Clients, Dealers and General Contractors which are in charge of designing and realizing a new metro, tram and railway superstructure, and furthermore we can provide support to new constructions, reopenings and restorations.
DESIGNING SUPPORT Studio Macetti provides engineering support to designing of railway, metro and tram superstructures, focusing on the choice of the typology of superstructure, basing on design, construction and maintenance constraints. Technological constraints Environmental constraints (noise vibration urban context) Budgetary and financial targets Maintenance Verification matrix Superstructure typology
DESIGN Studio Macetti self-manages Preliminary, Final and Construction Design of the superstructure of railways, tramways and metro systems, following the latest regulations, for new projects as well as for the renewal of former lines, providing also on-purpose maintenance plans.

RAIL WORKS RECORD CLIENT PROJECT DESCRIPTION Railway connection MILAN PASSANTE superstructure 2nd Lot Bologna-Verona railway line Crevalcore-Nogara section Completion of the new Affori Railway Station Railway connection from Bari airport and Bari City center, combined with Bar Milan Passante railway connection removal of turnouts and setting of a suitable fitting new track. The track (5.000 m) runs entirely in tunnel and was designed and realized with a superstructure with concrete sleepers embedded in a concrete cast for the reduction of noise and vibration to the surrounding buildings. Use of different typologies of turnouts and communications in line with related kind of superstructure. Track on traditional ballasted superstructure. The track (110 km) runs entirely on embankment. Design and realisation of noise barriers made of concrete and clay, extended for 13.000 sqm. Design and construction of Affori Railway station - Ferrovienord Milano, included civil works, plants and traditional ballasted superstructure (1500 m). The superstructure has been designed and realized on traditional ballasted system. The track (30.8 km) runs on cut, tunnel and embankment. In order to reduce vibration, in special areas has been laid under-ballast antivibrational mat. Design and realisation of removal works of two turnouts in order to renew the proper track at Dateo Station Milano Passante. Railway line Verona Brennero Galleria SCILIAR Design and realisation of removal works of two turnouts in order to renew the proper track into SCILIAR Brennero tunnel
METRO WORKS RECORD CLIENT PROJECT CARACHTERISTICS Milan Metro Line 2 Famagosta-Assago section Milan Metro Line 2 Famagosta- Abbiategrasso Line Linea 3 Metropolitana di Milano Tratta Zara - Maciachini nea 3 Metropolitana di lano Tratta Maciachini- Comasina Genoa Metro - De Ferrari and Brignole stations tana Università h (ARABIA AUDITA) s Noura Bint aman University Superstructure on ballasted milano modificato system. Track (10 km) runs partially in tunnels and partially on city ground surface. Realisation of superstructure with Milano Massivo e Milano Modificato systems. The track (3,5 km) runs entirely in tunnel with many turnouts and communication, including a hub with 4 turnouts and a junction. Milano Massivo superstructure has been realised to dampem noise and vibration at most. It is the first section of underground realized with this system. The track (2,5 km) runs entirely in tunnel. Milano Massivo superstructure has been realised in order to dampen noise and vibration and to reduce maintenance at most. The track (7,4 km) runs entirely in tunnel. In order to solve some problems related to the vehicle envelope, the height of the system has been reduced The track (2,7 km) runs in tunnel and has been realised with metro superstructure typology on precast concrete slabs laid on elastomeric mat for dampening noise and vibrations. Technical and production support to the construction of innovative ballastless superstructure. On site activities: Realisation of Design for the main contractor, Training of technical and production workers from main contractor, Material orders specifications and quality control procedures, Supply of technical and production managers and skilled workers, Surveying activities management, Work program and materials supply management. The track (27,6 km) runs on viaduct, except depot.
