Cascade Tunnel Operations (HD)

This video highlights daily operations at the East Portal of the 7.8 mile long Cascade Tunnel located in Byrne, WA, near the Stevens Pass Ski Area. This tunnel is the longest rail tunnel in the western US and is used by Amtrak and freight trains. This tunnel replaced the Old Cascade Tunnel after the Wellington Disaster of March 1st 1910 and has an interesting history.

[@spartemex2784]

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).

Oh geez. They could have put a little wye on each end for the electric locomotive then put the main locomotive in neutral for the trip through the tunnel.

[@marzsit9833]

in the early days the electric locomotives worked well but when travel through the tunnel increased, the electric locomotives became a big bottleneck in the operation so they had to go away to improve speed. it would have been different if the entire rail line was electric, but only the run through the tunnel was.

I've been told by an " old timer" that if you feel uncomfortable the best thing to do is lay down next to the tunnel wall and outside edge of the rails until the train passes. I have done this in my young and dumb days and it works well, my best advice if you have to go through a tunnel is to wait and follow a train ( do to train timetables ) as they are less likely to send back to back ( so to speak)

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

[@tonyf.8858]

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.

[@jackshittle]

You had to basically water board yourselves to keep alive. First house I ever bought was in Lake Stevens (I'm from NJ). We used to go to Lake Chelan, Chelan Falls Park, Orondo, Lake Wenatchee all the time (camping, hotels, rental house etc.) Got to see Roger Waters play at The Gorge. We would buy so many Ranier cherries & cherry juice at the road side stands that I would eat/drink all of it until I was ready to vomit. Also rented a cabin in Mazama one Thanksgiving.

[@tonyf.8858]

@@kishascape Since you weren't there, you don't know. During the fruit picking season, which the train went into the heart of apple country here in WA state, the authorities used to "look the other way" as long as you jumped the train OUTSIDE of the train yard, at the Seattle end and you had to jump off when the train when it slowed down to 10-15 miles per hour at the Wenatchee train yard end. If you were caught inside the train yards you were "fair game". The apple industry and WA state relied heavily on migrant workers to get there and pick the apples and pears. There, you learned something new today. Feel any smarter? I don't think this "tolerance policy" exists anymore. Has anyone out there hopped a freight through the tunnel in recent years?

[@DanMeyer80]

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.

[@MrNeptunebob]

I wonder how, if the fans are not running while the trains are in there but afterwards, how do Amtrak passengers not get gassed with the fumes? I doubt if the coaches are airtight. Also are the fans blowing air in or sucking it out?

[@DanMeyer80]

Coming back on 8, the fans were on when we exited the tunnel. On 7 they come on after we went in. Amtrak trains being lighter the engines dont put out as much exhaust as freights do. Bottom line, this tunnel made the trip worth every penny I paid to take it

[@garybulwinkle82]

I live about five miles from the tunnel in Montana and we're pretty far from the Flathead! It was funny the gate closed and was blowing the exhaust along with the train as it was going the same way as the air was pushed!??

Yeah I hope there’s something to check for leaning before entering the tunnel, because I’ve seen some intermodals go buy with a shifted load in the container and the top leaning to the side, sometimes up to a foot.

[@CaptainRon13]

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.

[@menguardingtheirownwallets6791]

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. Sometimes they do own additional 'yard property' nearby, so that might be a problem too.

[@irongoatrocky2343]

guess again! when the Great Northern and other western railroads were built the had ROW that was 5MI either side of the tracks! a lot of that was put in hands of sub companies in the case of Great Northern it was The Glacier Park Company, many areas GP Co still owns a good share of ROW

I was very intrigued with your introduction about how the ventilation system for the Cascade Tunnel came to be. But when I read the last part I was kinda disappointed.

Guys like you who have the time and resources to go to these places and document them is great for guys like me who don't but get to admire them from afar as it where when you make your video available for public viewing. I understand that security is tight because we live in such paranoid times. But when security is too tight, it becomes difficult to document them. And that's too bad. I do understand why though. I would like to go there to admire the engineering but also to do some fishing! That looks like a good spot. Thanks for posting the this video.

Norfolk RR got really bossy in our town. Try to bust people for being on train property. Even people who lives right at the tracks. The town fought back in ways that I had no idea they had the power to do. The town banned any train blocking an intersection for more than 3 minutes. 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. A warrant was issued for the top executive for failure to appear. He was arrested. That got their attention. They don't bother anyone anymore. This was about 25 years ago though.

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.)

[@TheEulerID]

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]

I don’t think that necessarily meant efficient in terms of the traction itself (electric almost certainly being superior, although it can depend on the system used) but more on the side of “operational efficiency” as you’ve described in your second paragraph.

[@ArtStoneUS]

The GBT has other issues other then exhaust... Temperature. The enormous pressure created by the overlying rock mass of up to 2300 meters drives the rock temperature up to 50 degrees Celsius. Ventilated temperature is 30-32 degrees Celsius.

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.

[@jasonbabila6006]

HeartlandTuber The fans blows the smoke out the other (west) end, the flush time is shorter after a westbound train versus after an eastbound train, it’s down hill westbound.

[@wesleyhurd3574]

@@jasonbabila6006 I think the movement of the westbound train itself probably helps to push air out the west end of the tunnel. Conversely, if they ran the fans full force against an eastbound train, it would probably slow the train down noticeably and cause the locomotive to work harder. That would create even more smoke than normal.

The only differences were that: 1) If I'm not mistaken, the Galleria dell'Appennino (Apennines Tunnel) didn't have doors unlike the Cascade Tunnel 2) The ventilation fans were steam powered, whilst on the Cascade Tunnel (like other tunnels in North America including Flathead, Moffat and Mount MacDonald) the fans are electric powered The ventilation system is no longer in use since the line was electrified in 1927 More here it.wikipedia.org/wiki/Galleria_dell%27Appennino (in Italian)

High clear green signal after the door opens and the fans turn off slowly

[@jeffryblackmon4846]

Those double stacks come very close to touching the tunnel archway. Good video.

Most railroads are always private property and I would get consent from the railroad first before I go to the off-limits areas for filming. They are trying to keep freeloaders from sneaking on the trains for free rides along with vandalism and getting seriously hurt.

[@timnewman1172]

I used to have to do work near railroad ROW, BNSF were probably the most accomodating people to work with, UP was hands-down the WORST!!!

[@tacomarailmultimedia1486]

This is why i clearly dont trust myself going in that tunnel... even on cold days...

[@kirkzevola5004]

Why do they leave one fan on while Eastbound trains are passing inside the tunnel?

[@marzsit9833]

an eastbound train will be displacing the air inside the tunnel like a piston, forcing it around the train and out the west end. one blower is needed to provide make-up air. but, when a train is moving westbound it will tend to create a vacuum behind it, so both blowers are needed to provide enough ventilation.

[@Northeastern_Railfan]

Why dose the tunnle close after a train goes through it? What’s the facility next to it? I have so many questions

[@denisetindall1487]

I like train videos videos on KZbin 👍

[@ReflectedMiles]

Another Amtrak loco insufficiency day. Since they already depend on the freights for the rest of their infrastructure, they might as well just have them provide power and power crewing, also.

[@jamesmurray8558]

I would cross Stevens Pass going to Cle Elm Ranger Station. Also went to the ski area.

[@daddywoofdawg]

so where is the intake for the fans and the exhaust ports how big are the fans?

[@gabrielstravels]

1:26 why is there a BNSF locomotive hauling an Amtrak train? What happened to that P-42 behind the BNSF locomotive?

[@pootispiker2866]

I've seen that happen from a few times, it's usually due to control system problems with the p42s. They work fine while trailing, though.

[@alconk7129]

Is that fans that spool up when the door closes?

[@aaa7189]

What do they do in a derailment ??

[@MrZlodeus]

4:40 holy shit, what a sound! *AWOOOOOOO!!!* ...but the one at 7:50 is even better. *ALAAAAAARM!!* 😁 ANd the blowers take quite long to wind down.

[@xXDrocenXx]

As an European, i didn't understand at first. Than disaster, someone's story of half died at the end and the lack of an power line got me finally. The fumes, they using diesel trains and I thought, why they don't have by us such doors. But why such a system? Why no ventilation system like as in an car tunnel? Should do the same, or is it not enough?

[@pootispiker2866]

It's not enough. These are not your piddly little trains like in europe. The freight trains operating in this tunnel always have at least two locomotives running under heavy throttle because of the steep grades. There is also the issue with clearance with the excess height cars that are also not present in europe.

[@xXDrocenXx]

@@pootispiker2866 Electricity and also passenger trains are the magic words. Long havy fright trains would interfere with the passenger trains. In Switzerland they have stopped the DB to drive in it, because they where mostly late and would result in many lateness. So they said no more. Also by me in Austria they overtake more and more DB trains. And because of that, the fright trains are not that long as by you. If you running late, penalties kicking in and most lines are state owned, so you now know what they will get ($€£). Longer trains are slow and need more space.

[@pootispiker2866]

@@xXDrocenXx I don't know if you realized what I said but freight traffic absolutely dominates American rail. Longer trains are also not necessarily slower, the railroads here just add more locomotives and give way to amtrak whereever possible.

[@MK0272]

Why would a BNSF locomotive be pulling an AMTRAK train? Particularly since the train already had an AMTRAK engine?

[@NotADoctor558]

Why was that BNSF locomotive pulling an entire Amtrak train at 1:23?

[@Generaleletric5102]

It’s a rescue the p42 probably had promlems

[@MegaAnticorruptos]

I can see a big Electric substation, a lot of wires everywhere, Electric facilities besides a railway but a Diesel Engine because there isn't any wire to supply the railway, Very intelligent.

[@federico339]

Then what would you do? Electrify the tunnel There are no electric locomotives using this route. Brilliant

[@fetchstixRHD]

The intro stated that diesel traction was “more efficient” than electric, probably taking into account that you’d either need a change of locomotive, an electro-diesel one, or otherwise electrify a much larger distance of track so that electric locomotives make sense operationally.

[@mgk920]

Prior to ventilation, GN operated this line between Skykomish and Wenatchee, WA with electric locomotives, using a 12.5 KvAC overhead catenary wire, swapping power between steam and the electric locomotives at those end points. The replacement of steam with diesel locomotives prompted GN to rethink the tunnel's electrification. With more recent fuel price spikes, there certainly is a potential to have to restring the 'wire', but at the cost of no longer being able to run double stacked containers and tri-level auto racks (and Amtrak Superliners), besides the startup costs.

[@diegorhoenisch62]

@@fetchstixRHD The writer of the introduction is apparently unaware that the train at the beginning of their video is a diesel-electric locomotive. It has nothing to do with efficiency and everything to do with costs(i.e. electrification has a high initial cost). The decision to run diesels is a short-sighted one, but it's rather typical. Cheers, Alan Tomlinson

[@pootispiker2866]

Electric trains aren't used on American freights. Excess height cars prohibit such things. Get a job.

Nice action Steve.

[@stavinaircaeruleum2275]

What's the wind pressure inside the tunnel when it's ventilating? Is the door one solid metal plate or multiple? Why do you have to stand back from the gate 50 feet?

[@sheppardpat47]

Pretty sure it's not that much pressure, it just ventilates the fumes

[@hectorperezcintas5970]

a question because the tunnel closes, that is, because there is a door that closes?

[@spencerbass7142]

Two questions. Do you think there are any cutthroat trout in the creek and what is the speed limit through the 7.8 mile long tunnel. Interesting video and quite an engineering feat. Thank you.

[@norrisgarcia]

I'm a locomotive engineer and have made a few hundred trips through that tunnel in the last 5 years. The speed limit is 25mph through the tunnel and as far as cutthroat trout , it too far up the creek.

[@Mike-01234]

Wonder how they keep animals from getting in there before the door closes

[@thunderegg670]

Derailment in that tunnel must be interesting..

[@HookerHeels]

Oh god....

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.

[@CapStar362]

so does anyone have footage of the fans themselves and controls? or is this entire thing autonomous with remote operation
