The AGV acronym for French: Alstom offers the AGV in configurations from seven to fourteen carriages, seating to persons. The trains are constructed from units comprising three cars each with one transformer and two traction electronics packages located underneath the cars and single-car driver-trailers. Design sgv the train took place through the early s, with a prototype, “Pegase”produced in Italian transport company NTV ordered 25 trains in with service that began in According to Alstom, the advantages of the AGV are: The first design studies relating to the AGV were made in Initial specifications were for a train with distributed traction total power 7.

The design would retain the articulated Jacobs bogie of the TGV. The new design was the first high-speed train design in modern times that had inter-vehicle articulation and distributed traction.

The trainsets were to be made up of modules of 3-car sets aletom two powered bogies per module. The traction electronics used two taps per transformer per module, each powering two parallel connected inverters, with a separate inverter for each motor.

There were two carriage designs: The initial AGV design incorporated a number of new features: Both technologies had been previously trialled on TGV sets. The carriages were constructed from aluminium alloy alstok used on the TGV Duplex.

The transformerswhich weigh 6. The interior structure was designed to allow easier refurbishment and alteration to the passenger environment. The floor level is kept practically constant throughout the train, including at inter-coach connections.


Bypermanent-magnet synchronous motor technology had become mature enough to use in a commercial product, and was incorporated into the design allowing a alwtom instead of frame-mounted traction motor, with higher efficiency and lower overall weight. Alstom claimed operating and capital costs per seat were the same as a TGV Duplex.

The design was complete enough to be frozen by July Each 3-car module had either a transformer or one of two traction modules inverters located beneath a carriage. Additional trailer vehicles referred to as ‘key’ cars were to extend the train size beyond multiples of three.

The bogies are related to the type alstok on the TGV trains; in addition to the changes to traction motor type and installation, the bogies are constructed of a high tensile steel, for lighter weight, the bogie wheelbase is 3m as with the TGV.

Braking is by rheostatic braking and regenerative brakingin addition to triple disc brakes on trailer bogies for low speed braking. An eddy current brake was not fitted. By May prototype vehicles were being constructed for testing in Two coaches were constructed; a driving and an intermediate cab, with both trailer and motor bogies; for testing the units were attached to a four car TGV Reseau set. Dynamic tests included measuring traction motor, braking rheostat, transformer and inverter cooling under high-speed conditions, as well as aerodynamic tests on airconditioning system performance at high speed.

Byenabled by the availability of rare-earth magnets with high magnetic strength, Zgv had developed permanent-magnet synchronous motors Ag which were zlstom for rail vehicles.

They were smaller and had a higher efficiency than asynchronous motors and a higher abv ratio, as well as having the potential for lower noise levels. The transformers were mounted in the driving cars, with the other two cars of the three car modules each carrying a traction converter ONIX water cooledwhich also integrate auxiliary converters, the middle ‘key’ car carried auxiliary equipment under the carriage.


The HVAC equipment is mounted on the roof. Dynamic tests were completed by March Alstom submitted its bid to supply NTV with high-speed trains in March The company planned to launch a astom of services on the Turin – Milan – BolognaRome – Veniceand Bologna – Florence – Rome – Naples high-speed lines, with some trains from Naples running to Bari.

Initial services were planned for mid based on the delivery of the first trains in September From Wikipedia, the free encyclopedia. Where sources conflict more recent value is taken. Power-packed train proves AGV technology in record sprint”www.
