Agreed and the old emds are the hot rods of the rails especially the old 567s they sound like big block chevys nothing like a demonic locomotive growl be it GE or GM
They sure are, everything from the U-boats to the first generation GEVOs. Sadly the Tier 4 units sound like vacuum cleaners. I think the retirement of the tier 3 units will be the end of nice sounding diesels.
Also, under heavy load, they sometimes have *Soot.* (which has a certain romantic aspect…. It’s like traveling in time, much as if the prime mover was *steamy.* ) While going over the hills to and from LA, I could sometimes see a slight pall of darkness as the locomotives pulled hard. That trip turned me into a train nut. I’ll never hear the trains coming in and out of the tunnel near home quite the same.
I love how the AC4400CWs sound just like Amtrak P42DC Genesis locomotives. In fact, I actually drive the searchlight simulations AC4400CW in Train Simulator 2020.
@@SvenTSchixe that’s a very good question. HEP is short for head end power. Basically all passenger locomotives have an onboard generator to provide electricity for the passenger cars. Which would be from the main diesel engine or from a separate generator on the locomotive
In that case I have these catches for you ; ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-WX-rtJFxAoM.html , ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-JgFyUDJUbEI.html
Agreed. In my opinion, this is some of the best use of natural lighting I’ve ever seen for twilight/night railroad videos. Plus, the superb sound of fluttering locomotive throttle resonance produced by the sound deflection-echo with trackside industrial buildings. Outstanding.
@@EdmontonRails no class 1 railroad cleans engines and the reason for fires and mechanical problems is they just put them out there then never fix them
Does anyone happen to know why the GEVO exhaust note bites harder than the 7FDL? it's way more aggressive compared to the FDL... edit: my hypothesis here is that perhaps on the GEVO's, the system running the fuel injection and perhaps even maintaining the timing of the prime mover itself is more precise than in the AC44's, but that's based on very little knowledge on how these actually work at an intricate level.
At the top of the ES44AC's exhaust stack there is a large metal plate covering ~70% of the opening. This creates a lot of reverberation within the exhaust system and more pressure at the opening, I believe that is the primary factor. The cylinders of the GEVO are also physically larger than the 7FDL, however the tier 4 GEVOs sound like neutered vacuum cleaners so it must come down to the exhaust system.
@@EdmontonRails Ah, interesting, I wonder if this is there to improve compression in the system.... potentially improves combustion completion within the exhaust? Thank you for such a quick, concise, and informative reply as well; that was refreshing
@@EdmontonRails Ah ok, yes could heats the difference e.g. to those EMD 645 which do 16 strokes / turn = 4800 @ 300rp vs 2400 for the 4 strokes. Why a / when it‘s „with“? / looks like „or“ or some kind of relation. Confusing…
@@EdmontonRails Yeah, you feel thos sound waves on your chest. Also thanks to upload this video, I am really happy to hear those diesel engines and the motors and not those bloody crossing bells and horns.
I use this cool trick called searching for the video I want and watching the video I want, rather than complaining on a video that isn't advertised as what I wanted.
