It appears that BNSF is renumbering the GP28P locos 1590-1599 into 1540-1549. John Hill and Alec Holms both shot the 1541 which is ex 1591.
also alot of SD40-2 and SD39's are going into the 18xx and 19xx series. I assume that anything they own will end up here and 63xx-72xx will get filled with Gevos eventualy.
Also the SD40-2B's and the SD45-2B's are going to the low 300's the GP60B's are 325-347 so all there B units will be in the 300's I havent heard if the GP9B will be renumbered or sold, the later would be a sad day if it was.
