<p>[quote user="YoHo1975"]I didn't think it needed to be Tier 4. Why would it be any different from the other repowers? Amtrak California already has repowered F59s, so it's a known quantity.[/quote]</p> <p>EPA distinguishes between <em>freshly manufactured</em> (new or rebuilt with less 25% worth of used parts), <em>refurbished</em> (25-50% worth of new parts), and <em>remanufactured</em>. There are too many additional requirements to name here.</p> <p>Depending on the grade of rebuilt the emission limits are different.</p> <p>Since 2015 <em>freshly manufactured</em> and <em>refurbished</em> line-haul locomotive must be Tier 4 compliant.</p> <p>For <em>remanufactured</em> line-haul locomotive all depends on year of original manufacture. A <em>remanufactured</em> F59PHI needs to be Tier 1+ compliant.</p> <p>So all depends on the scope of the rebuilding program. But quite likely it will fall into the <em>refurbished</em> category needing Tier 4 compliance.<br />Regards, Volker</p> <p>Edit: Definition of remanufactured deleted and posted in my first post on the next side</p>
