The station was the send-off and return point for Diggers fighting in both world wars.
Hundreds of Gympie region residents volunteered for the Australian Imperial Expeditionary Force in WWI, including some 30 for the Light Horse Brigade as a reflection of the region's strong horseriding skills.
The trip includes lunch at the historic Gympie Station, followed by a special train service aboard the Mary Valley Rattler to Amamoor Staton.
Lunch starts from 11.45am, with the train departing for return to Gympie at 1pm and arriving at about 4pm.
Passengers will watch as the train is turned around on the Amamoor station's revolving platform for the return journey to Gympie.
