With the right hammer, yes.

That said, with these units NS now has two classes of locomotives with the 12N-710G3B engine: GP33 and GP59E. If this is deemed to be a success there are 37 GP38-3s on the roster that are derated GP50s. Could these be future candidates for a 710 transplant?  

Correct me if I'm wrong but I read that the GP38-3s rebuilt from GP50's had their as-built 16-645F engines removed and replaced with remanufactured 645E's. The reason supposedly being an oil line issue with the "F" engine that was difficult to correct in the rebuilding process.

 I know that this engine swap was done on the SD40E units the railroad has rebuilt from SD50s...

 I would suspect that the process was more capital intensive ($) than just derating the existing engines so I would doubt that NS would turn around and do a capital rebuild a second time..

CSX has converted SD50's to "SD40-3s" by derating the "F" series engines so not all railroads seem to share NS's concerns..

Yes, but the GP38-3 project started 11 years ago. These units will be ripe for another rebuild in a few short years.

I thought that aftermarket (GE) 645F blocks had the issues resolved.

Yep, looks exactly like the SD59MX and the SD30C. No NS design there. Only work they did was to follow the Instructions....on this one.

Radiators change has to be for split cooling, no?

Must be. The rebuild does not have NS' designed intercooler forward of the D/B blister. This looks to be a 'straight up' EMD concept for an ECO rebuild.

That is correct.  Probably the Norfolk Southern designed version like those used on theirGP59E's. They really are good over at the Juniata Shops.

"Greener" Norfolk Southern locomotives ready for testing
Posted by rdamon on Thursday, January 8, 2015 3:58 PM

http://hamptonroads.com/2015/01/greener-norfolk-southern-locomotives-ready-testing

Two new environmentally friendly locomotives are on track for use in the Chicago and Atlanta areas.

Norfolk Southern Corp. this week rolled out a pair of GP33ECO diesel-electric, switching locomotives at its Juniata Locomotive Shop in Altoona, Pa.

The locomotives, designed to generate fewer emissions, are the first of 25 to be built for Norfolk Southern by Electro-Motive Diesel Inc. They will be funded in part by $35 million from the federal Congestion Mitigation and Air Quality Improvement Program.
