I'm pretty sure there's all of one tunnel in WA and it's no longer used
for trains. I've walked through it, it's now in John Forrest NP, along
with a few bridges at what used to be National Park station. I thought
it about the same size/length/loading gauge as Clarence tunnel near Zig
Zag. Perhaps some Westralian can tell me why they felt the need for a
tunnel in the first place - you do the return part of the walk along the
formation that replaced it around the side of the hill and there's not
really a lot of overburden on top of the tunnel.
