Regent Street railway station, formerly known as the Mortuary railway station, was a railway station on Sydney's Rookwood Cemetery railway line. Funeral trains departed from the station, bound for Rookwood Cemetery. The station found later use as a part of Sydney Yard. The ornate Gothic building is still standing on the western side of Sydney Yard at Chippendale, close to Central railway station and Railway Square. It was added to the New South Wales State Heritage Register on 2 April 1999.

A funeral train carries a coffin or coffins (caskets) to a place of interment by railway. Funeral trains today are often reserved for leaders, national heroes, or government officials, as part of a state funeral, but in the past were sometimes the chief means of transporting coffins and mourners to graveyards. Many modern era funeral trains are hauled by operationally restored steam locomotives, due to the more romantic image of the steam train against more modern diesel or electric locomotives, although non-steam powered funeral trains have been used.
