Since 2006, BNSF's locomotives designated for yard work or local trains have been painted in the "Heritage IV" scheme. Somewhat of a simplified form of the "Heritage III" scheme, "Heritage IV" is virtually identical to the original "Heritage I" scheme, albeit with black instead of dark green, and the current "Nike Swoosh" BNSF logo. Locomotives such as SD40-2's, GP38's, GP60M's and SD60M's have been painted in this scheme. In October 2017 nine GE B40-8W locomotives rebuilt by GE were painted into this scheme.
