In the recent years, VALE committed to achieve a cleaner and renewable company activity by aligning itself with the "Sustainable Development Goals" agenda, established by the UN in 2015 and aiming at sustainability goals for the year 2030. One of the initiatives includes the electrification of the Carajas Iron Railroad (EFC). This paper discusses concepts that were developed after extensive operation data analysis and discussions with VALE's collaborators. The ideas summarized could be part of the solution towards achieving the electrification of the Carajas Iron Railroad through the implementation of catenaries in the Açailândia Hills sector and the retrofit of the diesel electric locomotives to operate in dual mode or hybrid traction.
