Eastern Railroad Discussion > any update on NS 4800?

A few years ago, NS used a tier 4, 710 engine on a four-axle rebuild:

New NS GP34ECO (trainorders.com)

They claimed that it met the emission standards but promptly put it in storage.

Did the locomotive not really meet the standards, or was it put in storage account operating costs (or not even operating properly)?

I appreciate any updates.

The locomotive was tested mostly in the north in Pennsylvania yards (Altoona, Conway, Harrisburg, ect.). I'm not sure if it met the expectations they wanted, but it was not a very good engine when it came to shifting and power. The unit is currently stored in Enola yard.

OpenKnuckle, I appreciate that info.

I sure would like to know the inside story but I think you have given the best account so far.
 

So the thing was probably slippery to begin with so lets put a really big engine in it, that should
make it much better. Sorta like a 427 side oiler in a Pinto!

A bit like a GP40-2, but with 12 cylinders instead of 16. Doesn't sound like excessive HP per axle with both engines putting out 3000 HP.
