Overview of the Budd CPTM 5550

Explore the CPTM 5550, a notable Electric Multiple Unit (EMU) that has served the São Paulo Metropolitan Train Company (CPTM) in Brazil.

This locomotive, part of the 5500 series, was originally built between 1978 and 1980 by a consortium including ACEC, Budd, Sorefame, and Villares.

Operating on a 1600 mm gauge and powered by a 3 kV DC electric system, the CPTM 5550 typically forms an 8-car trainset.

Between 2007 and 2010, these units underwent significant refurbishment by Bombardier, ensuring their continued operational relevance and modern standards.

The CPTM 5550 is a key element in the history of São Paulo's urban rail transport.
