Idk anything about oxygen levels and engines but that tunnel is 1100 feet long and the engines are in notch 8 so all their exaust builds up in the tunnels till they exit. The CN engine was putting out the most exaust
Also noticed another great thing you got besides the smoking diesel electrics and the monster sized BNSF reefer boxes that were oddities on the train. JB Hunt Intermodal has ventured into the 53-foot reefer container business. They had about eight stacked on the train...at least.
Nice recording of the Canadian SD70M-2. SHE was the only EMD on the mixed goods train. You could see smoke emanating even from the GEVO master and it's slave DPU. You could also see it coming from the helper C44-9W. But what surprised me was that bellowing exhaust from the Canadian National EMD SD70M-2. Now when you see an EMD smoking like that, it's really hard working under load and probably the hardest working.
For this reason, the FSRR 4100-4132 (Ferrosur) became FXE 4100-4132 (Ferromex) both of GrupoMéxico Transportes [GMXT]. Well, the machines died inside the tunnels of Veracruz south of Mexico. These machines now only operate outside Ferrosur territory. These roster are model SD70ACe as in the video.
Even the SP Snoots had this issue....deferred maintenance.....run 'em until they break..... ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-wXpTRpn_fuQ.html&ab_channel=1MTSRider
must go thru some air filters lol the last unit was barely running from dirty air from the first two units smoke…need to go back to the tunnel style air intakes
All modern 6 axle diesel power actually has their air intake in the same spot as the old tunnel motors. The GE Locos and EMD ACe's at least. The air intakes are the vents just above the walkway at the rear of the locos in my understanding
@@jacobpfeifertrains1998 the emd does too, just doesn’t use filters like the GE units did. they used actual air filters emd uses a weird style in front of the air charger
Am dat videoclip ul inapoi ca sa număr vagoanele . In afara de cele 4 locomotive ( 3 inainte si una in urma ) am numărat 91 vagoane. Iese la cineva mai multe la numărat ?
The SD70M-2's are rebuilds that are entirely based to standards and specifications of the SD70ACE's.Canadian National and Norfolk Southern own these units.As a matter of fact Norfolk Southern has removed some of them from storage and is rebuilding them again as SD70ICC's.
When a loco smokes like that, doesn't that indicate a malfunction of the engine? Can't sensors detect this? If the malfunction is detected, why isn't the train put into emergency with the loco shut down? I've seen several videos on youtube of not only smoke but fire coming out and yet they keep going as if the engineer has not idea what's happening. How can that be?
@@jacobpfeifertrains1998Sensors do indeed "notice" the engine being starved of oxygen and adjust the engine parameters accordingly before recovering. Since this is expected performance from the locomotive, it's pretty rare for a maintenence message to even be set and the computers don't detect anything to be wrong. Remember, trains have been making this trip for decades.
There is no mechanical problem whatsoever with these engines. The smoking is due to a lack of oxygen and you can see it clear once it exits the tunnel. Emergency braking is not something you just use willy nilly. It can derail your train, making a little bit of smoke the least of your problems.
@pootispiker2866 there was a BNSF dash 9 that blew a turbo in Tehachapi summer of 2022 it was the DPU. It made it quite a ways before a Railfan called it in and they got the train stopped. Started 4 fires. But this 70M-2 is just old and dirty. Its still spitting smoke as it rounds the corner. That tunnel is over 1000 feet long. Oxygen might play a tiny part but i doubt its the whole reason. All the exaust just built up in the tunnel and they are most likely in notch 8 full throttle
@@jacobpfeifertrains1998 exhaust doesn't contain much oxygen. Exhaust is built up in the tunnel that three big diesel engines are trying to ruin flat out in. Engines need oxygen. Two plus two.
This is the same location where the SP train did the same thing in 1991. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-wXpTRpn_fuQ.htmlsi=Dwj4ieyiu7A8P35i
@@Sacto1654😂😂 their is no “serious filtration”. It’s the same type of filter as your home AC. It offers no smoke filtration at all. The smoke is not an issue to the crew because it’s behind them. Notice when the locomotive exits the tunnel, there’s no smoke around the cab. The smoke is only at the rear of the lead locomotive, and then everything behind it.
It definitely wasn’t just the CN SD70M that was smoking. The BNSF ES44AC and Dash 9-44CW were also smoking hard, so why call out CN on its own? Got a beef with Canadian railroads that aren’t as obsessed with EPAs as the US is? Tier 2 and 3 locomotives are still commonplace and legal in Canada while the US is “going to war” with companies that still operate them.
Locomotives produced a lot more smoke than this back when cabooses were around. And don’t forget steam locomotives as well. But the smoke at the rear of the train is not as bad as you think. The Locomotives are long out of the tunnel by the time the caboose makes it into the tunnel, and the majority of the smoke has dissipated.
