Brazil has awarded a €110m contract to French company Alstom Transport to supply 48 metro cars and a new signalling system for its Brasilia metro network.
Alstom will add 12 four-car trains to the metro's existing fleet of 20 trains, with first deliveries expected in 2010.
The trains will be made of stainless steel and feature lowered floors and illuminated information boards indicating stations.
The company will also provide a signalling system for automatic train operation that will be installed throughout the network, including at stations and on trains.
The order is part of the city's plan to extend its network to 47km and add eight new stations to the existing 21.
The new trains and signalling system will help increase the network's daily single-line capacity from 150,000 to 300,000 and frequency between two trains from 4.5 minutes to 3 minutes.
