It was in the siding that an event took place to finalise the plans for the biggest invasion force ever massed by the British military, the D-Day landings.

On the 2nd June 1944, Winston Churchill, members of his war cabinet, President Eisenhower and the French leader Charles de Gaulle, the Canadian President William Lyon McKenzie King and the South African leader Jan Smuts, all met on the Royal train, in the siding at Droxford. Tens of thousands of troops were already camped throughout the area, preparing for the invasion of France. The leaders went on a morale boosting visit to the troops and then returned to the train to hold last minute talks about the invasion plans.

Droxford station was chosen as the meeting point because of its proximity to the troops, its secluded siding and proximity to a deep cutting. It was thought that in the event of an attack, the train could be pushed into the cutting, where it would be hard to see. Imagine what could have happened if news of this meeting had fallen into German hands.
