This topic flared up recently, because EMD has released a second demonstrator which is a GP9. The first was a GP40. For those not in the know, 710ECO is EMD's answer to genset switchers and the used loco market. It takes an old EMD loco and puts in an 8-710GC3-T2, new electricals and computers and such. They're advertising between 2000-3150HP. Here are the photos Here's the press release over a year old EMD - News I for one am intrigued by this. I suspect that such an engine could find a home on Short and branch lines across the US where multi-engine units just don't have the oomph. (I've heard people on other forums talk about the NRE units needing to run in 8 for an entire pull where a pair of geeps will do most of it in 5. ) Also there's PHL which essentially did this using cat engines or UP which had some GP50s repowered with large engines. Also, the electrical engineer in me wonders what an SD40 repower might look like and how it could play a part in the current economy where ethanol booms, but business in general isn't. It of course all depends on the cost for the rebuild, but I could see where if the TCO is right, rebuilt 40/45s are getting tier 2 equipped fuel efficient engines and soldiering on. I mean heck, the rent-a-wrecks are still in service anyway. You get the fuel costs down and it might look really attractive.
You mean the BL20? and the GP15 before it? I agree, EMD has tried it before, but in this case, the incentive may be there. These units are getting rebuilt into something new anyway. Whereas back then, the rebuild was kinda not needed.
Another thing that was pointed out was that EPA Tier 3 is going to be retroactive, so even the rent-a-wrecks may be off the rails soon. Also, apparently, one of the SD60MACs that was in Pueblo is at CEECO right now undergoing some sort of mods. Anyone know more? Also Also, anyone have an update on UPs SD60 exhaust mods they were doing in Roseville?
I think it's an old NdeM electric. I've seen those a couple of times dead in train going random places.
Nope... the GP2000 program was before the BL20-2. Just like this program (and unlike the BL20-2 and GP15s), it was intended to take in older GPs and repower them with 8-710s.
Yes, they will apply at the time of remanufacture, but it's fair to say that in the absense of any restriction, many of those units would be up for remanufacture. Many of them have gone through remanufacture. I'm trying to see if the EPA website better defines what remanufacture is. In either case, the point, which you have not disputed, is that there is a regulatory impetus that didn't exist at any previous point. remanufactured Tier 0 (it doesn't say anything about locos built prior to the 70s that I can see) are going to need to meet Tier 1. A Tier 2 solution would be very attractive. Heck you couldn't even switch to bio-diesel, because your NOx emissions would rise.
remanufacture (defined as “to replace, or inspect and qualify, each and every power assembly of a locomotive or locomotive engine, whether during a single maintenance event or cumulatively within a five-year period…” (see 61 FR 53102, October 4, 1996; 40 CFR 92.2)
I've been searching the internet and the only Reference I could find to the GP2000 said it was a product being talked about with NS, but it never made it anywhere because EMD wanted a bigger order commitment. They decided to buy GP59s instead. The implication, though it's never stated clearly is that this was going to be a from the ground up new product.
The impetus already exists... Teir 2 regs also apply to new and remanufactured locomotives. In essence, Teir 3 regs will bump up current standard to the next level (i.e, a rebuild that qualifies for Teir 1 standards today would be Teir 2 in 2012)
EMD pitched them to NS (along with GP59s) in an SD60 order negotiation circa 1987. They were to use older GP cores.
OK, well then I guess this topic is old hat and not worth discussing. Sorry I brought it up. anyone know what's up with the 60MAC at CEECO? //Cranky, because my DVD player is not playing my NWP DVD.
I never heard of these locomotives. Interesting that the GP40 rebuild looks the same as far as I can tell, while the GP9 reminds me of some Cat repowering jobs. If this catches on, looks like we'll be seeing classic EMD power on the rails for a very long time to come.
I think it will catch on (8-710s repowers in particular)), as there's no Teir 2 solution for 645s as of yet, and even if one becomes available, you're still saddled with a 16-645 in terms of fuel comsumption (122gph for 645s (i.e, Roots-blown 2000hp), 168 gph for 645Es (turbo 3000hp). 8 and 12 cyl 710s (8 for 2000hp, 12 for 3000hp) can provide the same or greater ratings with better fuel consumption numbers.
Here's some 12-710 fuel numbers to look at... keep in mind they're old... 12-710G3A (07/1988) TP ___ RPM ___ HP ___ GPH 8 ____ 904 __ 3030 __ 147.3 7 ____ 820 __ 2253 __ 116.7 6 ____ 729 __ 1502 __ 79.6 5 ____ 651 __ 1244 __ 67.1 4 ____ 568 __ 1000 __ 50.7 3 ____ 490 __ 675 ___ 34.8 2 ____ 343 __ 350 ___ 18.9 1 ____ 269 __ 191 ___ 13,1 Idle __ 200 __ 0 _____ 2.4 DB-6 _ 729 __ 0 _____ 18.6 DB-4 _ 568 __ 0 _____ 10.9 DB-1 _ 269 __ 0 _____ 4.4 Compared to a 16-645E3 ~ TP ____ GPH 8 ____ 167.7 7 ____ 146 6 ____ 106 5 ____ 79 4 ____ 57 3 ____ 41 2 ____ 25 1 ____ 8 Idle __ 5.5 LIdle _ 4.3 DB ___ 17
