Assembly
In general, starting with fully welded and eventually painted coaches, all activities needed for the construction, checks and final performance tests of individual vehicles and for the coupling and functional tests of trains are carried out.
All “special” processes are carried out by qualified personnel who apply specific procedures that even indicate what equipment to use for processing and what checks to carry out.
After the application of materials for for thermal and acoustic insulation and the floor, the wiring system is installed as well as the electrical panels and various electrical and electronic equipment.
Wiring is installed by highly qualified personnel and is subjected to final checks with specific electronic equipment to test their continuity, insulation and electric strength.
The pneumatic equipment and the air-conditioning and heating units with the relative pipes, as well as the toilets, power-packs, luggage compartments and doors with the relative mechanisms are also installed.
Prior to the assembling of the covering panels, a check is run on all the work carried out as well as a water tightness test as provided for by the relative “procedure”.
The covering panels, driver desks, interior furnishings and all additional components are then fitted, all with the quality standards expected by clients.
The vehicle is then put into the paint tunnel to complete the painting of its exterior and afterwards brought to the area for functional testing and the final inspection test.
The train is coupled on a 240 m-long railway track provided with a pit and equipped with synchronized lifters.
After being coupled with the bogies, the electrical and pneumatic connections are made and the levelling of the train is carried out.
The test cycle to verify the correct functioning of all the equipment and on-board systems (door system, airconditioning, toilets, fire protection system, passenger information system, battery charger, emergency inverters, etc.) is performed by highly professional personnel and equipped with all necessary hardware and software.
Below is a list of the main tests carried out on individual vehicles and trains:
- Air-tightness of pneumatic system
- Brake system
- Door and access system
- Toilets
- Emergency inverters
- LV and MV distribution
- Power-pack
- Automatic couplers
- Air-conditioning/heating
- Fire protection system
- Emergency loop
- Video surveillance
- Passenger information system
- Automatic train control system
After all the tests have been completed, the final checks are carried out; then the train is prepared to be delivered.
