ViaMobilidade Series 8900

The ViaMobilidade Series 8900 is a class of electric multiple units built by Alstom to operate on ViaMobilidade Lines 8-Diamond and 9-Emerald in São Paulo. The first train was delivered in 2023 and is already in service. Each composition was built to the new pattern adopted by CPTM, with air conditioning, eight cars and free gangways allowing access to all of the cars, and based on the Series 9000 project. During the concession process of Lines 8 and 9 the acquisition of 30 new trains by the future operator was a contractual clause, later increased to 34 trains. On 20 April 2021 the state government declared the ViaMobilidade Linhas 8 e 9 consortium, of Grupo CCR and RuasInvest, the winner. Three months after the concession contract signing ViaMobilidade chose Alstom to build 36 trains, in a total of 288 cars, which began to be manufactured at a new Alstom plant in Taubaté; after the COVID-19 pandemic Alstom faced difficulties in importing electronic parts and delayed the delivery of the trains.
