How long is this tunnel?

I always though Kaimai tunnel in NZ is longer at 8879m, closely follow by Rimutaka tunnel (8798m)and Otiria tunnel at 8566m

The Rhyndaston Tunnel is 955m.  The longest tunnel in Australia is the Ski Tube at 6303m - the longest tunnel on a "traditional" railway is the Bylong tunnel (near Ulan, NSW) at 1975m.

New Zealand has three tunnels longer than 8000m - Otira, Rimutaka and Kaimai, the latter at 8879m is the longest in the Southern Hemisphere.  Tunelão tunnel in Brazil is 8645m, the longest tunnel in South America.

Well i think its 1.5kms long.

**EDIT** Dutton Bay is right and he bet me to it! Smile

The Rhyndaston tunnel had to be widened in the 1960s to take 8' high ISO shipping containers.  Now that there are containers even higher, does this tunnel have to be enlarged again?

Well most wagons have a deck height of 900mm or a little bit more.
Also i think the other year they redone all the track though the tunnel, but i don't think they droped the track down.

Whats the highest containers now days?. I think i need to take more pics of wagon loads

Containers are 8', 8' 6", 9', 9' 6".

There may even be 10' and 10'6".

The tunnel is not as long as some of the others but is pretty taxing on the locomotives due to it being on a 1in40 grade at the end of just under 10km of 1in40 grade... not to mention the condition of the locomotives...

Was up there tonight:



Not the greatest photographic conditions in the world, but conditions at the portal seldom are.

In building this tunnel did they learn from the experience of other tunnels?

When was it built?  Are there any intermediate ventilation shafts?  Does it count as a "rathole" tunnel?
  tasrail2100 Chief Commissioner

I assume it was one of the first tunnels built in the state, being 1873-1876 and then being widened in 1964/65.

There is one ventilation shaft in the middle somewhere but I am yet to find the point where it comes out.

I added a video of a train going up through the tunnel onto Youtube today...

10' are in use, but when I worked for a company that exports via containers and sends containers to the west both on a large scale) from Cen Qld, 10's didn't go OS.

Woy Woy tunnel is also quite long, I believe close to a mile, this may not be the longest, but its claim to fame would be that its double tracked, sparked and probably one of the busiest outside the UG CBD stuff. It also used to be fairly quick being rated at 115 when I used to commute on it in the 80's. But I believe that despite a multiple million dollar rebuild of the track bed in the 80's, like everything else in NSW under railcorp, its been slowed to 80(?).

Nice clip. The sound of the different engine types working hard together is neat.

The tunnel can take the old Seapack 11' or 11'6" boxes on standard wagons. The track was lowered again a little in the last few years, but that was more for ventilation than actual limiting size.

Added another video, this one is all about the sound....

Give it about 35 seconds.  It's from the 20/01/2006, and is mentioned here: http://www.railpage.com.au/f-t11312762.htm

could this example be the answer for Rhyndaston?

There's been a crew working at Rhyndaston over the winter. They've cleared the line and the area around the tunnel entrance of all vegetation. I am told it is in preparation for a retractable door to be installed over the tunnel’s entrance, a door which is supposed to help funnel smoke fumes away. I've been waiting for it to be finished, I'm curious to see how it works.

Similar to the previously mentioned Otira tunnel.

Rhyndaston Tunnel is a relatively shallow tunnel, I wonder whether they will eventually get around to cutting the top out?
  siroch Locomotive Driver

While the tunnel is indeed relatively shallow, the stability of the ground in this area is not the best, requiring (a) very shallow battering or (b) significant cutting reinforcement.  Ultimately the future of any tunnel "upgrade" is directly correlated to the mass/volume of freight offering south-north.  Any reduction in zinc or paper wouldn't justify much in the way of "upgrade".

Bypassing Rhyndaston Tunnel and the entire Brighton - Antill Ponds sections entirely via the Jordan River Valley (Elderslie, Hunting Ground, Apsley, Lower Marshes, etc.) would be far more more worthwhile to get a Southern Line with a consistant 80 kph average, rather than bothering with daylighting Rhyndaston Tunnel.

There hasn't been any work done at Rhyndaston since Oct-2011. As far as I know there have been no further preperations made, like mountings, cable laying, signals etc. I was begining to wonder whether theyve given up on the idea of installing the planned door.

How the door works! (and anyone see mistakes please correct).


When train goes up hill, its pumping out lots of smoke and pretty much the air is moving along with locos (anyon stand on UG metro station will know what I mean as you feel the train coming) so last loco gets lots of hot smoky exhaust around it, rather than cooler clean air, not good for loco people or performance.

So I believe what they do is place a door at the top of the grad porthole and so as train moves up the hill, door closes and the air has no where to go and must run past the sides of the trains making the air around the locos cooler and cleaner for the people and DEL's to breath.

With Otira after every train pass there is a minimum timeframe before the next train can follow as the tunnel is vented with extraction fans. On the loaded coal trains there are the normal 3 locos + 2 bankers working their guts out up the hill, so about 6000-8000kW of diesel fumes.

I'm afraid these are not even close to the longest. Tunnel 4 of the Cuajone line in Peru is 14,700 meters long.
