The '''EMD SD22ECO''' is a {{convert|2150|hp|abbr=on|lk=in|sigfig=3}} [[AAR wheel arrangement#C-C|C-C]] [[diesel-electric locomotive]] rebuilt by [[Electro-Motive Diesel]].  It is, along with the [[EMD GP22ECO|GP22ECO]], primarily the application of a conversion kit to an existing [[EMD SD40]]-type locomotive.  This involves replacing the existing [[Prime mover (locomotive)|prime mover]] with an [[United States Environmental Protection Agency|EPA]] [[United States emission standards|Tier-II]]-compliant [[Turbocharger|turbocharged]] [[V8 engine|V8]] [[EMD 710|710G3A-T2]], with [[electronic fuel injection]].  The prime mover is mated to an AR10 alternator for traction power, a CA6 alternator for control power, and a computerized control system.<ref>{{Cite web |title=New 710ECO Repower Products Provide High Performance for Low and Medium Horsepower Applications |url=http://www.emdiesels.com/emdweb/products/pdf/EMD_710ECO_Repower_Solutions.pdf |url-status=dead |archive-url=https://web.archive.org/web/20090718044710/http://www.emdiesels.com/emdweb/products/pdf/EMD_710ECO_Repower_Solutions.pdf |archive-date=18 July 2009 |access-date=27 August 2009 |website=www.emdiesels.com}}</ref> This conversion does not alter the external appearance of the locomotive. 

The [[Kansas City Southern Railway]] and [[Kansas City Southern de México]] were the only railroads to have rebuilt SD40s into SD22ECOs.<ref>{{Cite web |date=22 June 2009 |title=KCS Rolls Out EMD 710ECO™ Repower Locomotives |url=http://www.emdiesels.com/emdweb/company/more/062209_kcsrepower.html |url-status=dead |archive-url=https://web.archive.org/web/20090717034954/http://www.emdiesels.com/emdweb/company/more/062209_kcsrepower.html |archive-date=17 July 2009 |access-date=27 August 2009 |website=www.emdiesels.com}}</ref><ref>{{Cite web |date=23 June 2009 |title=EMD delivers first two 'repowered' locomotives to KCS |url=https://www.progressiverailroading.com/rail_industry_trends/news/EMD-delivers-first-two-repowered-locomotives-to-KCS--20706 |url-status=live |archive-url=https://web.archive.org/web/20171222221838/http://www.progressiverailroading.com/rail_industry_trends/news/EMD-delivers-first-two-repowered-locomotives-to-KCS--20706 |archive-date=22 December 2017 |access-date=2024-01-13 |website=Progressive Railroading |language=en}}</ref>
