About the doors from wikipedia: as a train enters the west portal of the tunnel, a red-and-white-checkered door closes on the east portal and huge fans blow in cool air through a second portal to help the diesel engines. As long as the train is within the tunnel, the fans work with reduced power to avoid pressure problems. When the train is approximately halfway through the tunnel, the door opens in earnest. Once the train has cleared the tunnel, the door closes again and the fans operate for 20 to 30 minutes with maximum power to clear the tunnel of exhaust before the next train passes through. In the opposite direction, the door opens when the train is within 0.6 miles (1 km).

I took an Amtrak ride from Cleveland, Ohio to Edmunds, Washington, for only one reason, because ever since I learned about Cascade Tunnel I wanted to go through it. So I took that long trip just to go through the tunnel. Also I timed it how long it took us to go through the tunnel, it was 15 minutes and about 20 seconds at 30 mph. Added bonus of the trip was going through the 7.1 mile long Flathead Tunnel in Montana, that one took us a little over 8 minutes to go through at 50 mph.

I think it's designed to break if hit by a train

A friend of mine and I hopped a freight train in the town of Skykomish on the west side and hitched a ride to Wenatchee. We jumped on to an empty car about 25 cars behind the engines as there were quite a few others in the cars closest to the engines and we found out the hard way why they were so close to the engines. The fumes were so strong that we had to take our t-shirts off and soak them in water from a canteen and breathe through them. I think it took about 20 minutes or so to go through the tunnel but it seemed like much longer because we thought we would die before we got to the other end. I was very sick after we emerged from that tunnel. The second time I hopped the fright, a year later, I got aboard a car much closer to the engine. Oh, our t-shirts were brown where we were breathing through them! Oh, it was apple picking season and that's why we were going east to Wenatchee and this was in Sept. 1974.

They banned any train traffic after 11pm until 8 am. Of course Norfolk RR ignored the ordinances. The police caught one train stopped and handed them the tickets. Norfolk didn't show up for court.

Railway property is usually from 1 to 1.5 times the length of one locomotive from the nearest rail. So just stand way back about 70 to 100 feet from the rails themselves and usually, that means you are well off of railroad property.

I’d like to have that fan system for my computer :3

Hi Chris, the best way to remove the diesel exhaust is to create a “positive pressure “ within the tunnel. The way to do that in this application is to turn of the fans at the clean end of the tunnel, a low the exhaust out of the other end. However, you can’t have both ends open to do this, because you will not develop enough pressure in the tunnel to evacuate all the exhaust. Big opening to suck in clean air, small discharge to exhaust, at a higher pressure.

I am surprised at the small size of the fans in use there. The Link stations use much larger fans (and more volume).

I've drive past (over!) that so many times and didn't know that was the east end of the tunnel. Thanks!

Pretty interesting the challenges made by having the technology to build a nearly 8 mile long tunnel! Thanks for this. Has anyone but me watched this all the way through? Is that the measure of a true train fan? 😜 I work on a steam tourist operation and things just take time working on the railroad, you just can't rush it, so I am used to waiting around for something to happen but being ready to move immediately!

It's strange what YT will send one's way, but ironically I found it interesting. Kept thinking of the old 30's cliff hangers when the door to the secret tunnel opens and closes.😃

At the 5:00 minute mark, door closes, fans ramp up. Is it exhausting or intaking area at that moment at that end of the tunnel? Great video. We went through this tunnel on our way via AmTrak from Chicago to Seattle a few years ago.

The major rail terminals in NYC are all fed by underground tunnels, and the trains that go in and out of them must be electrically powered. But at times, in the passenger area of Grand Central Terminal and Penn Station,l, I have smelled diesel exhaust - when I reported it to a railroad employee, he said that once in a while a train has to be pushed or pulled into the station by an auxiliary engine, which might be diesel. (And this is probably related to the main tunnel under the Hudson River, which is ridiculously in need of repair after nearly 100 years of operation.)

I'm not sure I believe the stuff in the introduction about diesel being able to pull freight trains through a tunnel more efficiently that electric (I'll given them steam though). There are literally dozens of rail tunnels in the world ranging down from the 57km (35 mile) Gotthard Base Tunnel, and they are, as far as I can tell without exception, operated by electric traction which vastly reduces the need for kludges like 800hp fans to clear out the fumes. Surely the real reason for diesel traction isn't it's inherent superiority, but because of the (understandable) lack of long distance electrified lines in the USA. It's simply not viable to use electric traction as that would mean electrifying the whole line (or using electric/diesel hybrids just for a short section). Electrification was apparently used for a while, but for a relatively small part of the system it wasn't cost effective. Hence this is a bit of a kludge brought about be the fact that the US long distance railway system is dominated by diesel.

@fetchstixRHD

Very nice video and fun to watch. Have a nice day.

Good audio capture of the fans coming on. I would like to take my field recorder and a shotgun mic up there for some audio samples.

Where are the fans and do they blow air into the tunnel or suck air from the tunnel?

All those road runner cartoons finally make sense!

@Steve Larson @SteveLarson - Looking for the owner. Pentrex Railroad Videos would like to use your footage. We do, of course, pay for footage. KZread will not allow any contact information here, so please reply here and we will figure out how to get in touch.

Thanks, great vid, but I believe it is Berne, not Byrne, WA.

Is being in the tunnel 2 miles with no door closure normal?

What's that sound inside of the tunnel?

Sounds like boredom and notch 6 for half an hour for an engineer. Unless we have engine problems. Then there's a lot of cussing. Most conductors fall asleep in there.

We have a tunnel here in NZ that is very similar called the Otira tunnel. Its 5.3 miles long but it has a 1 in 33 gradient. Like the Cascade Tunnel, it was electrified once, but that was removed, a group of GE U26C locos were modified to run this tunnel and a door and fan system much like this one was fitted

I'm in NZ as well. When I saw the thumbnail for this vid, before I'd read the title I thought it was the Otira. Very similar system and operation.

I have a question. A two parter. Do the crew in the cab of the first locomotive, smell exhaust from their own locomotive as they pass in the tunnel? And second, can passengers who are in passenger trains, smell the exhaust from their own locomotives?

As a passenger I can say that yes, you do smell the diesel exhaust from the locomotives when passing through very long tunnels.

@@FishKepr I thank you. I didn't think the seals on the windows could keep out all smells. Not healthy for passengers and crew. I thought exhaust fans were installed at various points along the route in the tunnel, to suck out the exhaust as trains went thru. Guess the cost to have that done correctly is very expensive. We have another reason to get away from using oil products.

Saw a steam locomotive at the California Railway museum in Sacramento lately where they reversed the design and put the cab at the front of the locomotive. That kept the crew from passing out from fumes in long tunnels, so apparently it is a problem! en.wikipedia.org/wiki/Cab_forward

If somebody stood there while that door was closing would they be squashed ? On the Queen Mary a steel bulk head water tight door was closing and young cabin boy tried to squeeze thru but he got crushed!

Not gonna lie, it’s cool to see a BNSF train lead an Amtrak train

Can anyone explain exactly how the ventilation system works, please?

its simple, i think. The fans in the tunnel pull air in from one end, and push the exhaust out the other end of the tunnel.

@@erictremblay4940 the fans are to the left of the tunnel entrance. If they left the door open, much of that air would deflect out that way instead of being forced completely through the tunnel to flush the exhaust out.

I found a lengthy explanation via a Google search. The procedures are different depending on whether the train is east or westbound. Don't remember the link but wasn't hard to find.

Wait so why does it do that can’t you get trapped?

Those grain cars are very likely going to the Tacoma grain elevator with corn being the most likely cargo, or maybe soy beans. Local 23 I.L.W.U. west coast longshoremen will unload them.

A tunnel that has a closing door? Never heard of that

Is there a need for a door?

With the door closed and the fans drawing air in from another opening (otherwise they would need fans hanging over the track and that risks impacts, and the wind loads of passing trains) it makes sure the air is sent the correct way with enough air pressure differential to achieve the required ventilation. If the doors were open, it would be easier for air blown in at (for example) the East end to simply blow back out the east doors, rather than go through the tunnel.

Nice action Steve.
