 In the 1980s, the DRC railcars were the fastest train in Australia by average speed, running the 107 kilometres from Ararat to Hamilton on Mondays and Saturdays in 72 minutes, an average of 89 km/h.The railcars were regularly used on the Stony Point service after 1984, following the reintroduction of passenger services on that line, but by the early 1990s, regular failures saw them replaced by locomotive-hauled trains.The DRCs were also used on the Leongatha line for a few years, after the line was reopened in 1984, but were replaced by a locomotive-hauled train towing three MTH carriages.
