History
In 1985, the first updates to the system were made, several new locomotives arrived, allowing more horsepower and thus, faster and safer travel, the original locomotives would still be active, but, with the exclusion of the F40PHs, they were often used during non-peak times. The line also dabbled in Nippon Sharyo Peachliner II cars, taking advantage of the lower wages in Japan compared to the US.

In 1998, MARTA received their first MPI F40PH-3C engine.

In 2011, MARTA Commuter Rail acquired a set of locomotives, which became their first dual-mode engines.
