of coal trains with an underpass at Hanbury west of Waratah allowing trains to reach Port Waratah without having to interface with the northern pair of tracks. In 2006 the Sandgate Flyover was opened to similarly allow trains to access Kooragang Island. As at December 2012 there were 50 to 60 coal trains per day up to 1.5 kilometres in length. To alleviate congestion which frequently sees loaded trains queuing, in November 2013 construction commenced on five relief roads at Hexham that will be located between the two running lines, with the westbound line relocated further south. This will allow coal trains to be pass one another and reach the ports in a more logical order. It is scheduled for completion in 2015. Aurizon, East Coast Rail and Pacific National both provide locomotives and freight wagons to operate coal trains. East Coast Rail provide crews to operate Xstrata owned rolling stock, with Pacific National doing likewise for Whitehaven Coal and Southern Shorthaul Railroad for Centennial Coal.

PWCS leases the land on which the port is situated from the Government of New South Wales under an agreement which states that the port is maintained as a 'common user facility'. The coal export facilities operated by PWCS have a total capacity of 133 million tonnes per annum (Mtpa): Carrington coal terminal has a shiploading capacity of 25 Mtpa. It has berth space for two vessels and shiploading facilities that operate at 2,500 tonnes per hour (tph). Carrington Coal Terminal is able to accept coal deliveries by either road or rail. Kooragang coal terminal has a shiploading capacity of 108 Mtpa. It has berth space for four vessels and shiploading facilities which can operate at 10,500 tph. Kooragang Coal Terminal is able to accept coal deliveries by rail only. Kooragang coal terminal has been undergoing expansion due to demand since inception. Further expansion is currently underway to take
