Will the EMD SD40-2, SD50 & SD60 meet the Tier 4 emissions requirements in 2015?

Good Day,
Curious, will the EMD SD40-2, SD50 & SD60 meet the Tier 4 emissions requirements in 2015?
Regards,

They don't need to, unless I am much mistaken. As previously manufactured equipment, they do not fall under the auspices of the EPA Tier 4 emissions requirements.

If a locomotive has been remanufactured, then it would have to meet the EPA requirements.

Any new locomotives manufactured by EMD and GE after 2015 will need to meet Tier 4 requirements.

No.

Tier 4 will be very difficult to meet. NRE claims their N-Viromental locomotives will, but they are adding scrubbers to the exhaust which raises the height of the carbody/longhood to the current height of GE/EMD locomotives. The problem is that neither EMD or GE can do that to current current locomotives because of height restrictions.

As I've been told, "Meeting Tier 2 or Tier 3 isnt the challenge. That can be fixed relatively cheaply with software, kits, and/or prime movers. Its Tier 4 thats the problem". Who knows, in the next 4 years something may happen that might make it feasible. Then again I dont think any of those engines are required to make Tier 4.

+2, Absolutely Correct.

As a matter of fact you can even reman them as long as you dont pull the engine from the locomotive. Once you pull the engine then then it will change the emissions requirement.
