very few of the 13,000 "non-air" coal wagons and some of the steam locomotives of the northern coalfields survive at the Richmond Vale Railway Museum. The museum makes use of a short remaining part of the former Richmond Vale Railway. The NSW Rail Museum has on display two 10-ton "non-air" four-wheel wagons; one J & A Brown wagon from the northern coalfields and one South Bulli wagon from the southern coalfields. The former site of the coal wharves at Pyrmont on Darling Harbour is now occupied by the Australian National Maritime Museum. The environmental damage that was caused by the construction of the Balls Head Coal Loader at Waverton inspired the writer and poet, Henry Lawson, to write a poem, "The Sacrifice of Balls Head". Parts of the disused loader have been converted to public space—now known as the Coal Loader Centre for Sustainability—with the derelict loading wharf remaining safely off-limits. Ships are still moored at the unloading wharf, but the ships now are ones undergoing restoration. One of the tunnels beneath the stockpile platform still has a movable chute used by the original loading system. The site has interpretive signage that provides information covering in detail the history of the site. In June 2021, the coal loader site was added to tne NSW Heritage Register, but, by January 2023, the timber loading wharf was distorted and showing signs of impending collapse. The Blackwattle Bay coal facility and its gantry crane were largely intact, in 2002, when a master plan for the foreshore area envisaged their retention and adaptive reuse. The gantry crane was demolished at some time before 2007. A partial collapse of the coal bunker occurred as a result of a downpour on 12 February 2007 and some of the damaged structures were demolished in 2007. By September 2018, only a little of the Blackwattle Bay coal facility survived. The site was derelict and overgrown. There was a derelict brick building—the former gate-house—and one side of the coal bunker structure. The timber wharf had gone although the reclaimed land where the rest of the bunker stood remained. There were rusted remains of some coal handling equipment, including grabs and pieces of gantry crane structure. The NSW Government announced in 2016 that the Sydney Fish Markets would be relocated to the old wharf area adjoining Pyrmont Bridge Rd. That would allow the existing Fish Market site— in the shadow
