LOlz. The only difference in sound is that the less powerful 12-cylinder engine doesn't need as much scavenging, so the roots blowers are geared to run at a lower RPM.
too bad my city got rid of it's railyards. people complained it was too noisy when trains had to switch cars, and they also didn't like having to wait at the crossings either. it's videos like this, make me appreciate what my city once had.
Does one of those locos have a leaking exhaust manifold or connection? Think a GP 15 is what a Southern local crew used to park across from the Albemarle Hotel circa 1973,in Charlottesville VA. Would leave it idling all night in cold weather and a trainman told me never to put glycol antifreeze in those things because it had "overhead radiators"
Hey take a look at their exhaust systems, those are T models. Originally designed for tunnel service. Air intake is lowered to prevent it from choking the engine while in a long tunnel.
Nope. Only 28 GP15Ts were built, for the Chessie System and a Florida short line (not sure why they would have wanted tunnel units -- maybe Chessie decreased their order). However, standard GP15s have a roof profile that looks a lot like a tunnel unit. 545 is an ex-Chicago & Northwestern GP15-1. 731 is actually a rarity: it's an ex Mo-Pac GP15AC. Those are identical to a -1, but AC-powered. Only 34 were built.
And I just realised the "T" in GP15T stands for "turbo", not "tunnel". The regular GP15-1s have a 12-cylinder Roots-blown engine; the GP15Ts have an 8-cylinder turbocharged engine that generates the same power. (Was watching the video again and looked at the comments.)
Double lolz. Turbocharged EMDs have a single exhaust, these clearly have two, and the roots blower can clearly be heard at the higher throttle settings.
WASTE OF POWDER ..... Have seen one ( 1 ) SW1500 do the same kind of yard switching and pull one-hundred and fifty ( 150 ) loaded grain hoppers over one hundred ( 100 ) miles with NO PROBLEMS .....
When I worked on the MP back in the late 1960 ( to 1988 ). It was a grain train our of Kansas City to the grain elevator at Ama, Louisiana. The grain rain left KCMO with one SW1500, changed crews at Monroe, Louisiana ( they also fueled the engine ), then Alex, Louisiana then set grain train out at Ama Grain Elevator and tied up at Avondale Yard, Louisiana. I was the chief clerk on duty. We also had grain trains from the connection via New Orleans that went to the grain elevator in Myrtle Grove, Louisiana ( on the NO&GC ) which were pulled by the regular assigned SW1500 on the local. We used the SW1500 for yard switching ( at Avondale Yard and Race Street Yard on the TP/MP Terminal Railroad of New Orleans ), industry switching, and transfers to and from the SOU, IC, and to MP Race Street Yard in New Orleans. It was in the late 1970s when they started using GPs to do the yard switching.
That crew is pretty skilled on kicking cars! One after another with very little pause. They know what they're doing!
Teah... I could sit and watch (and listen) to that ALL day.
Love the stack talk of a non turbocharged EMD.
It's like music to my ears!
I love the sound of the GP15-1 throttling up. It sounds a whole bunch stronger than the GP38-2.

Thanks so much for putting up this video I like watching switching
thanks Dave
You cannot beat the sound of a 645E 12 cylinder non turbo (roots).
Great catch, those things really tend to roar loudly.
Great sounding loco's. There are a couple in North ave. yard in Chicago.
Awesome engines, powerful and they sound great! Fantastic video! I NEED one of these in HO scale now :)
Great sound ! Not much out there with that particular sound.
i love the sound of a EMD at work
it's actually at the East end of the yard.

Thanks, they sound awesome!
Que chido esta ay pa andar moviendo los fulgones
Same here!!!
Oh that sucks. I would hate to live somewhere with no tracks!

Oh yeah! Thanks!
What's in the tank car's?

+HoustonRailFan ™ The GP15-1 was developed about three years after the SD45T-2 in 1972.
essa gp15 tem ronco meio g12
É o mesmo motor das G22
O 645 V12 sem turbo de 1500hp

JimTB k where does that happen at
???????
JimTB where did you see one SW1500 pull 150 loaded cars over 100 miles? Where does that happen?

It must have been either the AC version or a MP15 version...not a standard SW series.
