hey would a BNSF (BNSF 6306 and 6307 have been repainted with the BNSF and the number on the side of the cab) SD40 and a BNSF GP50 [BNSF 3163] have turbos? the SD40s were built in late 1981 and the GP50 was built in early 1981.
on models (HO athearn GP50) they have the horn placed on the top of the cab but i was looking at some pics of a GP50 (BNSF 3151 http://archive.trainpix.com/bnsf/EMDORIG/GP50/3151.HTM ) and the horn (three chimer) was between the fans. also do class one railroads (i.e. BNSF, UP, CSX, [the big ones]) prefer three chimers? i model BNSF and most of there horns are three chimers.
what are the horns used by today’s railroads?
Both of those would. Both are 645-series engines.

hey does anbody have a locomotive list (i.e. GP7,GP50, SD40) with the type of engine series (i.e.645, 710 series engine)?
As far as engine sounds go, if you spend enough time with a particular 567 or 645 you get where you can recognise the individual engine. I’m a tug captain and I can tell the difference between the port and starboard engines just by each one of their sounds. There are a lot of things that will change the sound slighty on any installation. No two sound exactly the same. Slight differences in the exhaust, different amount of wear(tired ones will have a rattle to them), what accessories they have on them, how much carbon is in the exhaust and airboxes. Since my ears are tuned to EMD’s from sitting on top of two of them for weeks at a time, 24/7, I can tell(if I’m close enough) if it is one I’ve heard before.

Hey guys,
I’m uncertain as I don’t have the facts in front of me, but “I think” beginning with the GP50 and SD50 series, EMD switched over to the 710 series Bentnose Willie answered this question a long while back. I haven’t seen him post in a while.
To confirm or get better info, post the question over on the TRAINS Forum. Some of the guys over there are good sources of locomotive specs information.
According to this history, the GP50 and SD50 were 16-645’s. The last of the 645’s, as the GP60 was the debut of the 710 series.

Thanks RRinker!
Update:
Interesting twist to an issue brought up on the Soundtraxx Yahoo Forum regarding 1st and 2nd generation EMD locomotive sounds.
A point was made that the EMD GP38 / SD38 series is non-turbocharged. A modeler asked if it would be more accurate to install a Soundtraxx decoder with the 567 diesel sound instead of the 645 series sound since 567 series diesels were “generally” non-turbo.
On the flip side of this, the EMD GP20, which was equipped with a 567 diesel, was turbocharged!
This is one of those “Paradox” situations or the exception rather than the rule. Debate was going back and forth!
Regarding the EMD 38 series:
I maintained that even though they were non turbo, the GP38s, to me, still do not sound like 567 equipped locomotives like the old GP7s and GP9s I used to see running around back in the late 70s-early 80s. . I’ve been around the prototype EMDs countless times. The exhaust on GP38s is less pronounced than a 567 and has a slightly higher pitch. The old 567s had more of a “baritone” sound to them and were louder and “throatier” than a 645 equipped unit. So in an HO GP38, I would still install a decoder that has the 645 series sound, even though the turbocharger sound is included.
If I were modeling an EMD GP20, I would stick with the 567 sound decoder for it even though one is not available with the turbo sound. (By the way, weren’t the New York Central GP20s non turbo?)
Anyway, just my 2 cents guys. Hopefully within the next year or two we will see an explosion of sound decoders on the market with a much greater variety of sound (and lower prices!). [8D][;)]

Most railroads today use Nathan K5s (K5LA, K5HA, K5H), Nathan P3s, and Leslie ST3s or 5s.
