TMB to purchase 42 trains to replace the oldest models on the L1 and L3Taking the oldest trains on the metro system out of service will speed up the renewal process and lead to improved reliability, at the same time eliminating part of the asbestos present in the network.
The procurement commission for the governing board of TMB today approved the process to start the purchase of 42 trains, each with five carriages, for the network metro. The trains will replace the 3000 and 4000 series, which account for the majority of trains on lines 1 and 3.
The next step will be the publication of the tender announcement, enabling manufacturers to present their offers. The competition is divided into two lots, one for 24 Iberian-gauge trains for line 1, and another for 18 standard-gauge trains for line 3. Manufacturers may present offers for either of the lots, or an offer for both of them, with a combined value of 447.2 million euros.
Trains from the 1980s
The 42 new trains will replace the eighteen series 3000 and twenty-four series 4000 trains, which are very similar in age and characteristics. These models date back thirty years and are the oldest on the city’s metro system. As is normal for trains, roughly halfway through their working life they were renovated to upgrade technology and improve reliability and interior comfort.
Of the 210 carriages in the series 3000 and 4000 trains, minor proportions of non-friable asbestos (which releases no fibres) have been found in 94, as an ingredient in the soundproofing paint on parts of their chassis and covers. The paint is in good condition and therefore represents no risks for users or staff, but it would be unfeasible to remove it and so TMB has opted to speed up the replacement of all the trains in these series as part of the plan to eliminate asbestos from the metro network.
TMB approved the purchase of 12 new trains for the metro system in March 2018, to increase the number of units operating on lines 1, 3, 4 and 5. The trains are being made by CAF and Alstom and should start being delivered at the end of this year, providing a boost for services the lines where demand is greatest.
