On April 1, 1952, South Australia introduced the triple-decker train in Adelaide, aimed at offering stunning views of landscapes like the Adelaide Hills and Barossa Valley. It featured three levels: an upper deck for sightseeing, a middle level for seating, and a lower deck for dining and bike storage. However, the trains quickly proved unstable, swaying on curves and causing issues with station platforms and overhead bridges. The design also failed to navigate tunnels, and altering tracks was deemed impractical. After six months, the experiment was abandoned, with the trains repurposed for other uses, including as dining cars and even a chicken coop in the Clare Valley. Despite its failure, the triple-decker train remains a quirky chapter in South Australia's transport history.
