Utah railway had some locomotives with 3600 series caterpillar engines and when the train would get into the tunnel all the subsequent engines would start shutting down cause the engine would intake that much air. So I can imagine it’s not the air filters as it is the lack of air flow to properly supply the intake of all those engines in the tunnel.
The Sd-45's appear to be all gone. MRL put a lot of effort into making their new EMD units work over the top. But before the electronic controls, the NP hired a lot of operators.
Not possible. Virtually all westbounds require 4-5 unit helpers. No way to make those unmanned DPUs as they have to return to Helena to assist the next train. And they're not needed anymore once they top the summit.
Right now there's a 5.9 Cummins guy bragging to his buddies how he made 2000HP on the dyno when in reality he has an air intake and a tuner making 350 horses. LOL. These locomotives are making some power.
With all that smoke I thought it was a Russian train. Seriously though, I got seasick watching because of all the camera movement and zooming. A tripod would help, and no zooming. Otherwise, it was a great video.
When cprail built mcdonald tunnel 1980s they found out trains stall due exhaust was not big enough pick up smoke from locomotive so they have upgrade systems it was hell cost fix that yup millions overbudget for this small details put learning curve for cprail on new tunnels.😮
That’s one long train 🚂 I think I counted eight engines and lost count of the number of wagons. Was that goal they were carrying? Looks like no ventilation shafts in the tunnel
Looks like decreasing levels of O2 for the following units in the tunnel. The lead engine gets pretty clean air, but the following units are using air with decreased levels of O2 and causes incomplete combustion of the fuel on the trailing units, which the reason for the black smoke. When the engines exit the tunnels, the O2 levels return to normal and the exhaust on the following units clears up. RR diesels really use a lot of air as well as fuel when running at full throttle.
@@KandWRailroader, I don't know. Looking at the video, the lead cab comes out of the tunnel fairly smoke free. Being back in one of the trailing cabs is another matter, as anyone back there would need some protection.
Ma le locomotive intercalate e quella di spinta in coda sono presenziate da macchinisti o no...? / But are the interleaved locomotives and the pusher locomotives manned by drivers or not...?
Thanks airing and sharing the outstanding video with magnificent locomotives.Railfanning endeavors are promising.Bliss
Love your videos thank you
Thank you!
Sweet catch!
When I saw the thumbnail, I thought it's a BigBoy as a helper. 😅
Thank you for that video! 😎👍
😁
You hiked in closer than I ever do.
I just have a really, really, really, really long telephoto lens. 😉
The best vantage point is to hike up the side of the hill to the right and maybe 200 ft from the tunnel opening. I've superb photos from that spot.
wonderfull more co2 look how green the trees are
i bet the bats in that tunnel have there own oxygen supply.
😂😂😂
😂

I would not want to be a hobo in that tunnel
The prepared hobos bring masks with them for these tunnels.
Great video, Its amazing that they would have a crew in the helpers and not DPU'ed with all that smoke in the tunnel.

90% of the heavies wouldn’t make it over the MRL without helpers. They need them and dpus.

Mighty intense video if you watch/listen with headphones on. Almost as good as being there yourself! Almost.
wow , thats a lot of coal that train is working
What weight of coal is in one of those wagons? 100 tons?
220k-246k lbs roughly...
121 tonnes
143 tons. Source. I load these trains
Right now there's a 5.9 Cummins guy bragging to his buddies how he made 2000HP on the dyno when in reality he has an air intake and a tuner making 350 horses. LOL. These locomotives are making some power.
Gotta roll some coal to roll that coal!
Haha, nice
👍👍
Sorry I have to ask with all the smoke do the engineers have to wear a mask thanks in advance for the help
The crew on the mid-train locomotives wear respirators in the tunnel.
Was this the end of the tunnel that collapsed years ago?
Yes, I believe so.
In todays health care environment that is a questionable operation, nobody should work in that environment
They are required to have respirators on board. Whether they take the time to actually put them on is anyone's guess.

I appreciate the feedback. Thank you.

A perfect example of why Cabforwards were designed for use in the West.
Difference between western trains and eastern trains- no graffiti
Lots of flat spots on those coal hoppers for it being a unit train.
I would not want to be in the last engine 🤭
I feel sorry for the crew on the other train.
I was just going to make the same comment... hope there's a breeze and they give it a few minutes to air out....
Great video BNSF and MRL Railroads main lines trains friends cep updates your beautiful video friends
Excellent video
Thanks!
The amount of air that a DE locomotive requires is amazing. something like 7000 cu ft a minute for an old sd40 sized engine
No emissions standards have been harmed during the shooting of this video ? Impressive.
😂
Deep breaths y’all, it’ll soon clear!
That’s one long train 🚂 I think I counted eight engines and lost count of the number of wagons. Was that goal they were carrying? Looks like no ventilation shafts in the tunnel
Does anyonne know why the locomotives smoke so much in the tunnel but stop immediately when they exit? Is it super hot inside or something?
Looks like decreasing levels of O2 for the following units in the tunnel. The lead engine gets pretty clean air, but the following units are using air with decreased levels of O2 and causes incomplete combustion of the fuel on the trailing units, which the reason for the black smoke. When the engines exit the tunnels, the O2 levels return to normal and the exhaust on the following units clears up. RR diesels really use a lot of air as well as fuel when running at full throttle.
Instead of puling in fresh air, they pull in a lot of smoke, leading to incomplete combustion and probably noticable reduction in power.
@@edhoran1709 Is the air so bad in the tunnel for the crew that they have to wear masks or something?
@@KandWRailroader, I don't know. Looking at the video, the lead cab comes out of the tunnel fairly smoke free. Being back in one of the trailing cabs is another matter, as anyone back there would need some protection.
Yes, the helper crew has respirators.
When I lived in Helena MT, I got up to Blossburg Tunnel a couple times.
That's nothing compared to what it was before they shortened the tunnel length.
Show
I’m guessing diesel engines on railroads don’t have to run DEF like trucks have to
Do they never change the air filters in those things?
Yup, these engines have *soot!*
Canadian Pacific on the rear end too....
What’s her face Greta would appreciate that display of horsepower. St.Paul,Minnesota.
For sure 😂
that is so cool and all.
Nice video thanks
Thanks!
why are the coal cars not covered ??
Coal is waterproof😶
@@woods840 no not water proof it is sprayed which rejects water
Why would it be covered? They load from the top and the environmental impact isn’t big enough to cover them.
@greta thunderburger.
How many wagons?
130 is a normal coal set
Ma le locomotive intercalate e quella di spinta in coda sono presenziate da macchinisti o no...? / But are the interleaved locomotives and the pusher locomotives manned by drivers or not...?
Yes, manned drivers
