Network 2 runs back into the hillside behind the junction of Queensway, Queen's Rd East, and Hennessy Rd.
It has three portals. From west to east they are portals 50, 51 and 52 respectively. The portals are still clearly visible today. #51 is bricked up, but #50 and #52 have (locked) grey metal doors for access.
Information about this network has been removed from the public records at the Civil Engineering Library, probably because it runs under land that was used by the British Army, and is now used by the PLA.
