The Royal Australian Naval Bridging Train was a unique unit of the Royal Australian Navy. It was active only during the First World War, where it served in the Gallipoli and the Sinai and Palestine Campaigns. The Train was formed in February 1915 and stood down in May 1917. Throughout its existence, it was composed of Royal Australian Naval Reservists under the command of Lieutenant Commander Leighton Bracegirdle. Normally under the command of the British IX Corps, the Train also supported the I ANZAC Corps and Imperial Camel Corps in the defence of the Suez Canal.
They were the only Australian naval unit serving in a European theatre of war. They were therefore bent on proving, both to the Royal Navy and to the British Army, that they could overcome any difficulties.[2]

The Train was Australia's most decorated naval unit of the First World War, with more than 20 decorations awarded to its sailors.
