In 1979, after tests and concessions of the first patents (by England, followed by Japan, Germany, United States, France, Brazil, amongst others), Empresa Brasileira de Transportes Urbanos (EBTU) became a partner in the project and, in the same year, the agreement between Coester and EBTU was signed. In 1983, the construction of the Pilot Line began. With approximately 1 kilometer, Aeromovel made its first trip in Porto Alegre (downtown) along Avenida Loureiro da Silva. In 1986, the project was concluded, through financing from the Financier of Studies and Projects (FINEP).
