The old bridge over the Hunter River at Hexham opened in 1952 has a lifting span—no longer in use—which allowed the ‘sixty milers’ to access the one coal loader that was upstream of the bridge's location. The Stockton Bridge opened in 1971 has a 30m clearance to allow ships to use the North Channel of the Hunter River that leads to Hexham. The Hexham coal loaders are all gone. The last of the Coal & Allied facilities at Hexham—the Hexham Coal Washery—was demolished in 1989. Only a small part of the South Maitland Railway remained in use for coal traffic by 2018. A 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. Parts of the Ball's Head Coal Loader at Waverton 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. 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 is derelict and overgrown. There is a derelict brick building—the former gate-house—and one side of the coal bunker structure. The timber wharf is gone although the reclaimed land where the rest of the bunker stood remains.
