It’s said there are nearly 100 kms of tunnels in the cliffs near The 3 Sisters, Katoomba. Coal mining began in that area in 1878 and there were about 40 mines at various times.<\/p>\n

The tunnel is\u00a0ABANDONED, CLOSED<\/span> & EXTREMELY DANGEROUS<\/span><\/strong><\/span><\/h3>\n

The mining history in the Jamison Valley, Katoomba around the Scenic Railway and Narrow Neck is incredible. One of the early achievements was the construction of the\u00a0Mt Rennie Tunnel.<\/p>\n

\"\"<\/a><\/figure>\n

The Mt Rennie Tunnel runs under Narrow Neck Plateau, connecting the Megalong Valley with the Jamison Valley.<\/p>\n

It was built so oil shale from the Glen Shale Mine could be transported to the railway using the existing cable haulage facility, the Katoomba Incline, in the Jamison Valley.<\/p>\n

The tunnel is about 3 metres wide and about 1.2 metres high for most of its length. It was just large enough for the double-track tramway. It looks like the tunnel was dug from both ends. The Megalong Valley side is slightly lower. There is a larger space in the tunnel where the 2 levels meet.<\/p>\n

The tramway ran between the Mount Rennie tunnel through Narrow Neck and the Daylight Tunnel through the Katoomba coal mine.<\/p>\n

When mining was finished the Mt Rennie Tunnel portals were blocked.<\/p>\n
