The Otira Tunnel is a railway tunnel on the Midland Line in the South Island of New Zealand, between Otira and Arthur's Pass. It runs under the Southern Alps from Arthur's Pass to Otira - a length of over 8.5 kilometres (5.3 mi). The gradient is mainly 1 in 33, and the Otira end of the tunnel is over 250 m (820 ft) lower than the Arthur's Pass end. - ภาพยนตร์และแอนิเมชัน
Travelled through this tunnel on the Trans Alpine in 2016. Absolutely amazing engineering. Pity they did away with the electrics, though. They were just that bit different!
did a 3 week stint in otira in 1979.went through the tunnel a few times on jiggers and one time in an eo electric. remember one time we took a pole through on a jigger with trailer and a chain saw with instructions that if the pole fell off we were to cut it upas not to stop the trains
I travelled through the Otira tunnel in 1993 when I did the day trip Christchurch-Greymouth-Christchurch.
Thanx for the great cab ride.
This is the best light at the end of the tunnel ever, ☺.
Great video
Thanks for sharing with us
excellent ride cheers
Nice one Samo, I can smell the dynamic brake from here. 🙂
Good sound ....😊
Excellent! I don't know why but I was expecting the tunnel to be fairly rough hewn, much like the Homer tunnel near Milford Sound. I was surprised to see it fairly dry and well lined with concrete.
Also, hopefully this tunnel is not intersected by the alpine fault.😬
Apart from the ‘new’ fan door extension, at the northern portal, the tunnel is fully bricked.
The smooth sections in the roof are plastic sheeting to divert drip water from the tracks and direct them to the side drains. 🤓👍
GE dynamic brake fans in a confined space sound fantastic
Can we see a cab ride through Kaimai Tunnel?
Does the gradient inside the tunnel change slightly at about 7 minutes into the video, this is when the light coming in the western portal is first seen. Or is the tunnel too long to see the light?

Na its the same gradient throughout, the tiny tiny spot can be seen with the naked eye but the camera didn't pick it up
Any variation in grade is in inch/mile range and not generally perceptible. In the fight conditions you can see’portal to portal’ which gives you an idea just how straight this tunnel is. 👍
Does anyone know why this tunnel is not called the Arthur's Pass tunnel rather than the Otira tunnel?
Would assume because the loco depot and staff were stationed in Ōtira, and the banker staff still are.
Going back?
1:39 What was that for neglecting the overhead line?
Long a ago was electric trains before
wow
What speed would this of been?
30-40kmph?
Yeah 35Km/h through the tunnel
Does it get hard to breathe inside the locomotive?
Nah they have doors and fans to remove exhaust gases whilst the train is in the tunnel
@@samocooper9070 The doors only close for up hill trains.
But to answer the question, unless an uphill train stalls and is over run with exhaust gases, the lead loco is always moving into clean air.
Didn't know there was a triangle at Otira
Stub ends are long enough to cater to two Dx’s.
Where is the longest tunnel? 🙂
The Kaimai tunnel at 9.03km north of Tauranga, is NZs longest tunnel. The Rimutaka tunnel at 8.98km is Second on the list. Otira was NZs 1st longest tunnel. Followed by the Rimutaka tunnel in 1955. Then Kaimai in 1970ish.
This tunnel alone is bloody impressive and a 13 year teenager been in the cab heading down was and still is mind blowing, had a family member working for railways back in the day on the Trans alpine, will never forget this experience and from the top heading down that light at the end of this tunnel never got bigger until atleast 200 meters from the exit, brings back memories 👍 thanks for ur video awesome to wwtch

The folks who built this make todays look pathetic.
Claustrophobic!
