Wouldn't it work better if the fans would send the exhaust out of the top of the tunnel while air was drafted in from the opening of the tunnel. With that and the uphill grade of the tunnel, I think that would work better. But I'm no engineer. Just a dude with a thought.

This is a complex problem with that sizes. May the air flow direction is have to work oposit of train travel direction for safety reasons but the train is act like a piston so the exhausted gas was travel with and it gets pushed to the travelling direction. To move the exhausted gas to the travelling direction is need lots of feesh air has to be moved thru a gap around cargo it is more demanding than just push/suck the exhaust gas backward.

The air goes out the west portal. The west portal looks just like a “normal” tunnel portal. A train going the other direction doesn’t require ventilation because it is coasting downhill. I believe a short flush sequence is done after Westbound though.

Good video of *what* happens, just not really a how-it-works video…a deeper dive video might be cool. With a diagram showing where the fans are positioned, where the train is during the first blow… Many questions come to mind: What’s the point of the door opening and closing? (Wouldn’t fans successfully suck fresh air in regardless?) Does it work for Westbounds? Is it automated? Assume so…so have there ever been any door-related accidents? Could the driver stop the train in time if he saw the door was still closed? Is it really a door or is it more like a thick rubber curtain like you might find in a walk-in fridge? Is that system original to the tunnel? (When was the tunnel constructed?) Is this a common system for long tunnels in the US? Aww never mind - I’ll just Google it.

As a young boy, I had a couple opportunities to experience this tunnel. My dad was an engineer for the BN, still in the 70s my dad was able to be allowed to bring me to work. Since my grandparents were in the eastern central part of Washington, I could be taken to see them a few times that way. Later in the 80s, I was older and not so interested, and the BNRR and other such things had to be vigorously clamped down on. But watching this video is a nice reminder of those times The ventilation system might’ve been something he explained to me at the time, but today watching this, I’m blown away by how it works. (Pun intended)

My stepdad also worked as an engineer his whole life, And in the early 70's did work out of Skykomish for awhile. We lived in Auburn so we would go up and see him. I also got an opportunity to ride along, wasnt it fun back then. He normally ran the pusher engines so would be in back. Anyone that was on the back was required to wear respirators, but the night I got to go, he was in the leading locomotives no respirators required. We left Skykomish around 3 am so it was all dark during the ride up, and within a few minutes into the tunnel I was asleep. woke up soon after. Ended up having to take the train to Cashmere. There I took another nap, then we returned. I Remember them telling me to look out for mountain goats but I never seen any. Of course, soon after entering the tunnel west bound, I fell asleep. It was still a fun day for an 11-12 year old. A few years later I got to play Nightwatch man on a steam train he helped rebuild and run on the track between Concrete, and Mt Vernon. He was a great man. RIP Fred 'Blackie' Moser. I now live in Sultan Washington, and travel the pass multiple times a year and always look at that area when driving by.

@ interesting. I called my dad while I was still not beyond halfway through this video to ask him about the tunnel. He had some really interesting stories (well one was particularly interesting) I’m sure, but the one that he brought up was while he was on a helper engine somewhere in the middle of a mile long (I think he said it was that long, he’s not as sharp these days when recollecting his days that long ago. But it was mid or early 70s. The train had a brake line fail, while it was inside the mountain. So they had to shut down all the engines to stop making exhaust, while the brakemen searched for the broken hose line. It was a 4-5hour event by the time it was able to either start rolling again or to get out of the tunnel. Such a long train takes a long time to start moving, especially when it’s going the uphill direction. I’m assuming that meant they were eastbound, I don’t recall. Typically it was an hour or so journey from end to end, traveling as slow as they did. They always had to monitor the speed as well as the engines actual power levels, or they would overheat since airflow was essentially only the wind created by the ventilation fan systems. In truth I really don’t think I can remember much of my journey, except that I know I did it for sure one time. I have other memories of a (I think it was another line, but still up in the north cascades, the towns you mentioned. I can mostly recall Concrete, Skykomish and a couple others, but that is mostly from years later when I have traveled through hi-way2 when my girlfriend (now recently ex wife, mother of our two kids whom we camped and other stuff around Mt Baker and East of the mountains in Wenatchee in I will guess 96 or seven. I grew up mostly in federal way, 72 till I finished high school in 83, During this period. Before FW I had my earliest years in Des Moines, 67-72. Later in the 80s I lived for a couple years in auburn. 84-85 ish. Now I’m in Madison Wi. Dad retired in early 2000s, can’t remember the year. Your dad’s name didn’t immediately pop into my memory. Though it might later. I knew a bunch of RR people who dad worked with, one, the guy I bought my first car from, he lived on the western hillside of Kent I think, maybe Des Moines, 288th is coming to mind.

For the more Metric among us; This is *12,35km* long, and the difference in elevation is *190m.* 📏🇪🇺👍 I've been through this once, on a trip to Seattle about ten years back. Learning that the train takes a good 30 minutes to pass through it in the eastern direction (An average speed of just 15,5mph/24,8km/h), I'm glad I was travelling west! 🐌💨🚂😋 That said, I've never seen a tunnel ventilation system work like this in Europe; On the Channel Tunnel (30mi/50km) we have two intake shafts and use the central evacuation tunnel as the main ventilation duct. Taking the Cascade approach there would _blow_ Eurostar and Le Shuttles operations wide apart! 🌬🚄😋

When they were digging the tunnel originally they bored a vertical shaft down through the mountain, so that they could dig from both ends and also both directions from inside the mountain, thus cutting the construction time quite a bit. I've often wondered if that vertical shaft still exists. You'd think that if it did it might be pretty useful for ventilation, but I've never heard any mention of it. It's hard to imagine they filled it in after the tunnel was dug though, I mean what would be the point of that?

hallo all together I have a quick question. I am a traindriver in Germany. If we had such a tunnel with a door on each end, that door would be connected to a signal that a train canˋt hit the door (if everything is working as intendet). Now to my question, are the doors on Cascade Tunnel guarded by a signal or something else which brings the train to stop before it can crash into a closed door?
