The Heritage Park concept links a number of heritage sites through the rehabilitation of former industrial railway lines. The sites included in the overall heritage park concept are:

• Lithgow State Mine (City of Greater Lithgow Mining Museum)
• Lithgow Blast Furnace
• Lake Pillans
• Eskbank House (Lithgow & District Historical Society)
• Eskbank Goods Shed
• Eskbank Station
• Eskbank Locomotive Depot site

This is the second largest cultural heritage project in New South Wales. Current developments to link to the Zig Zag Railway will create the largest cultural heritage precinct in the state.
