Close to the western edge of Central Station there is a singular line servicing just one platform, the Mortuary Station aka Regent Street Station.
Opened in 1869 it ran special funeral trains to Rookwood Cemetery to the West, to Woronora Cemetery to the South and to Sandgate Cemetery to the North. It ceased this function in the mid-1930s, being used for animals until falling into general disuse. It has been restored and is listed by the National Trust - but stands idle. Locked. Patrolled.
These two images were printed in the Sydney Mail in 1901 just as the cemeteries were being "dismantled" in preparation for the 3rd incarnation of Central Station. On the left is the main entry to the Presbyterian Section which fronted Pitt Street and on the right is a view across the cemetery from Devonshire Street. The cemetery occupied the area bounded by Devonshire, Pitt/Regent, Chalmers and Eddy Avenue. Eddy Avenue is only 200m long and was named in 1898 after the recently deceased (1851 - 1897) Commissioner for Railways, Edward Eddy.
I can find no association between this line (built in 1869) and the Devonshire Street Cemetery (Brickfield Hill) which operated adjacent to it from 1820 until just before 1900. But the proximity is just too coincidental.
