Bronco, the BNSF has been down grading some of their SD40s to SD38s. What they are doing is removing the turbo and putting a roots on. Then the locomotive is used mostly in the yard. There is no advantage to having a turbo on a yard engine. It always appeared to me yard work tended clog up the turbo and increase maintenance. <br /> <br />EMDs SD 90s has the new H Block diesel it is a 4 stroke engine and has two true turbos. No gear drive at low RPMs.
