IAIS 508 start up with the famous “Whoop” Sound Effect!

I honestly didn’t expect to take off so much, but that’s alright! Thanks to everyone for all of the views and likes, if you like to see Iowa Interstate (and in general more locomotives) make sure to subscribe!

You most have great ears because i can't hear it.

Sounds a hit like a class 37 cold starting

[@gracie-C3]

Iowa interstate still has the best paint scheme of all the gevos, I just wish they would’ve painted the safety stripes on the rear like on the GPs and SDs

[@NishnaValleyRailVideos]

Unfortunate that the SD38-2s are still in storage, they would be nice to see here in Atlantic.

[@gracie-C3]

@@NishnaValleyRailVideos I think they still use the GPs for switching around newton and granger

[@NishnaValleyRailVideos]

@@gracie-C3 Only the PTC geeps are allowed to roam the IAIS system now, and I think only about 5 have PTC.

"WTF IS POSITIVE TRAIN CONTROL!?"🗣️🗣️🗣️🔥🔥🔥‼️‼️‼️🔊🔊🔊

[@nsrailfangaming5313]

Positive Train Control (PTC) systems are designed to prevent train-to-train collisions, over-speed derailments, incursions into established work zones, and movements of trains through switches left in the wrong position. On December 29, 2020, FRA announced that PTC technology is in operation on all 57,536 required freight and passenger railroad route miles, prior to the December 31, 2020 statutory deadline set forth by Congress. Furthermore, as of that date railroads had reported that interoperability has been achieved between each applicable host and tenant railroad that currently operates on PTC-governed main lines. In addition, as required, FRA certified that each host railroad’s PTC system complies with the technical requirements for PTC systems. This accomplishment was the culmination of over a decade of sustained and direct engagement and collaboration among FRA and the 41 railroads currently subject to the statutory mandate, including seven Class I railroads, Amtrak, 28 commuter railroads, 5 other freight railroads that host regularly scheduled intercity or commuter rail passenger service, as well as key railroad industry associations, material suppliers, and service providers.

mfw most railroads need PTC now

[@trevorthefoamer220]

@@NishnaValleyRailVideos not Iowa Interstate, thats the main reason why Amtrak isn't going to Iowa City. Since the owner doesn't like ptc.

[@NishnaValleyRailVideos]

@@trevorthefoamer220Unfortunately… not correct. The reason why Amtrak hasn’t begun service to Iowa City, etc. Is because of the lack of signal infrastructure. The main reason why we don’t see the GP38-2s/SD38-2s leading anymore is because they need PTC upgrades. The GP38-2s have been getting this updates along with AC units, but the SD38-2s still sit in storage for the moment.

Whoooop

[@swampysanta5445]

i think that whoop sound is the air compressor starting up

[@NishnaValleyRailVideos]

Correct.

[@slamdvw]

at about 0:45 you can hear the actual compressor motor start, it's kind of quiet.., about 2 seconds or so before you hear the compressor load up. (( whoop sound ))

[@NishnaValleyRailVideos]

That’s interesting, I wish I had a better camera/mic for this video. It was actually shot on a IPod Touch if I’m gonna be honest.

[@slamdvw]

@@NishnaValleyRailVideos not bad considering the distance from you to the unit! I just listened again, you can hear all the stuff going on, from the bell shutting off, to when the engine finally gets running. I think I have some start up videos on my channel - I may even have a compressor start in there. If not, I'll see if I can get one or two. I'm listening on a good set of speakers with a sub, can hear the thump of the exhaust as the cylinders pick up.

[@rocklandrailfan1761]

Very satisfying did you get any videos of it moving?

No I didn’t it shut off a few minutes after

Where's the whoop sound?

[@NishnaValleyRailVideos]

0:48. It’s a bit hard to hear.

[@amessman]

You are hearing an electric motor spin up the compressor assembly to match the engine speed. Then a clutch engages the compressor to the prime mover crank shaft. Then the valves close allowing the compressor to compress air. The valves are open by default as starting the compressor while they are closed would require a lot more energy.

[@NishnaValleyRailVideos]

That’s some interesting info, reminds me of how my AC works on my truck, uses engine RPM for the clutch instead of an actual compressor.
