are near their final withdrawal from service. On 23 December 2008, two new stations were inaugurated on Line A: Puan and Carabobo. The increased demand could be absorbed by the current fleet, with the reinforcement of two trains Fiat Materfer taken from the line D. A total of 95 La Brugeoise cars operate on Line A.

Spare parts for these trains are no longer available in the market so they have to be custom-made by request at Polvorín workshop, where La Brugeoise units and other Buenos Aires metro rolling stock are maintained and repaired by highly skilled and qualified personnel. According to Metrovías, Buenos Aires Metro private operator, every 20 days units undergo a routine check-up, while every four years heavy maintenance is performed. Despite their 96 years of uninterrupted service, La Brugeoise trains have one of the lowest mechanical failure averages in the network: 19 every 100,000 km.

The increased demand could be absorbed by the current fleet, with the reinforcement of two trains Fiat Materfer taken from the line D. A total of 95 La Brugeoise cars operate on Line A.

Spare parts for these trains are no longer available in the market so they have to be custom-made by request at Polvorín workshop, where La Brugeoise units and other Buenos Aires metro rolling stock are maintained and repaired by highly skilled and qualified personnel. According to Metrovías, Buenos Aires Metro private operator, every 20 days units undergo a routine check-up, while every four years heavy maintenance is performed. Despite their 96 years of uninterrupted service, La Brugeoise trains have one of the lowest mechanical failure averages in the network: 19 every 100,000 km.

The increased demand could be absorbed by the current fleet, with the reinforcement of two trains Fiat Materfer taken from the line D. A total of 95 La Brugeoise cars operate on Line A.

Spare parts for these trains are no longer available in the market so they have to be custom-made by request at Polvorín workshop, where La Brugeoise units and other Buenos Aires metro rolling stock are maintained and repaired by highly skilled and qualified personnel. According to Metrovías, Buenos Aires Metro private operator, every 20 days units undergo a routine check-up, while every four years heavy maintenance is performed. Despite their 96 years of uninterrupted service, La Brugeoise trains have one of the lowest mechanical failure averages in the network: 19 every 100,000 km.

are near their final withdrawal from service. On 23 December 2008, two new stations were inaugurated on Line A: Puan and Carabobo. The increased demand could be absorbed by the current fleet, with the reinforcement of two trains Fiat Materfer taken from the line D. A total of 95 La Brugeoise cars operate on Line A.

Spare parts for these trains are no longer available in the market so they have to be custom-made by request at Polvorín workshop, where La Brugeoise units and other Buenos Aires metro rolling stock are maintained and repaired by highly skilled and qualified personnel. According to Metrovías, Buenos Aires Metro private operator, every 20 days units undergo a routine check-up, while every four years heavy maintenance is performed. Despite their 96 years of uninterrupted service, La Brugeoise trains have one of the lowest mechanical failure averages in the network: 19 every 100,000 km.
