Description
The tunnel is 528 yards (483 m) long, and is approached on either side by 10-kilometre (6.2 mi) climbs at the
Construction of the tunnel was commenced by boring from both ends. The new line from Murrurundi had been finished up to the east of the tunnel to aid in the supply of materials, and the two bores had met with the tunnel navigable by foot.[7] By June 1876 the tunnel was enlarged and brick lined with track laid. The contractors engine made it through the tunnel by July 1876.[8] The line to Quirindi was opened in August 1877.[9]
Fumes
The Ardglen Tunnel is at the summit of
Proposed deviations
To cope with considerably increased coal traffic from north of the tunnel from 2010 and beyond, various deviations are proposed. These deviations can either keep the existing summit tunnel, or bore a much longer tunnel at a 200-metre (660 ft) lower elevation. The deviations that keep the existing tunnel increase the length of the line so as to ease the gradient to 1 in 80 which is the ruling gradient on the rest of the line to the port. The existing line would be retained for empty trains going the other way, so forming
Stations
The stations on either side of Ardglen Tunnel from the south are:
- crossing loop and start of ruling grades. Had a locomotive depot for bank enginesin steam days
- Pangela – closed short crossing loop on ruling gradient
- Ardglen Tunnel – summit
- Ardglen – medium length crossing loop and railway station, being further lengthened in 2010
- Kankool – short crossing loop on ruling gradient
- Willow Tree – medium length crossing loop and railway station and end of ruling grades
