Gruppo Aziende Italiane e Argentine (GAIA) was a consortium combining Italian and Argentine firms that produced diesel locomotives for Argentina's rail system under the supervision of Ferrocarriles Argentinos.
History
The Argentine company Fábrica Argentina de Locomotoras (FAdeL) initially commissioned Fiat Ferroviaria to supply 280 diesel engines intended for locomotive construction. However, after only 80 engines had been delivered, the 1955 military coup resulted in FAdeL's shutdown in 1956, causing the project to be discontinued.
In 1957, Ferrocarriles Argentinos engaged GAIA, a consortium composed of:
| Country | Company | Role |
|---|---|---|
| Italy | Fiat | Diesel engine manufacturing |
| Breda | Carbody and control systems | |
| O.M. | Carbody fabrication | |
| Pistoiesi | Carbody production | |
| Ansaldo | Traction motor supply | |
| Ercole Marelli | Project design and technology development | |
| Argentina | Siam Di Tella | Generators and traction motors |
| Cometarsa | Carbody assembly and manufacturing line |
The agreement tasked GAIA with producing 280 locomotives powered by Fiat engines, prioritizing the incorporation of Argentine components wherever possible. Two variants were manufactured: 130 units with 1300 HP and 150 units rated at 1050 HP.
Cometarsa assembled the initial 80 locomotives in Campana using exclusively Italian parts; subsequently, 60 locomotives featured engines produced domestically in Argentina; the last 145 units were entirely assembled locally between 1965 and 1970.
The first batch of 1300 HP locomotives (numbered 6201–6350) arrived in 1962 and were assigned to Mitre railway’s diesel branches (Victoria–Capilla del Señor and Villa Ballester–Zárate), as well as passenger services from Retiro to San Pedro and freight operations around Rosario.
GAIA locomotives also operated on the San Martín railway for both passenger and freight duties. In 1968, twenty locomotives were allocated to Sarmiento railway for passenger transport before their reassignment to the Roca railway in 1971. The Roca line received twenty units for local service routes to La Plata.
These locomotives were the first to feature Ferrocarriles Argentinos’ corporate colors of bordeaux, yellow, and red. During the late 1970s, certain units were retrofitted with Fiat A230 engines; however, these modifications did not meet performance expectations. By 1987, GAIA locomotives had been supplanted by ALCO 251B engines sourced from decommissioned RSD-16 models.
Following the privatization of Argentina’s railways in the early 1990s, remaining GAIA locomotives were distributed among various concessionaires: Nuevo Central Argentino acquired seventeen units, Metropolitano received four, Trenes de Buenos Aires obtained ten, while other locomotives were allocated between private companies and state operators. The state-owned FEMESA managed fourteen GAIA units during the transition period preceding privatization.
