Well, besides B23-7s and SD9s, BNSF has retired their GP7/9/10, GP15-1s, SW200s and SW1500s. I guess the 1500hp 645s in those GP15-1s and SW1500s are no longer good enough, since BNSF has plenty of 2000+ hp road switchers on hand. The MP15s aren’t on this list though.
Where did you get this list. The locomotives in black on the list are still in the computer. Thats a good chunk but not all of those locomotive models are gone. I am an engineer for BNSF and can give you by unit number GP7/9/10, GP15-1’s, SW1200’s and SW1500s in service. The B23-7s are all stored and most probably retired. There are still about a dozen or so SD9’s running around, they did just send six or seven to Topeka for storage. Here is one example. SD9 #1716 ex-BN 6119 nee-GN 592 ‘‘assigned to Grand Forks ND for use on yard lead, will doublehead with RCO engine’’. That was as of 5 seconds ago…
If there is a particular engine in question let me know, I can look it up for you. Thankfully theres representatives of each model still in active service. With exeption of the dash 7’s.
The GP38M,s Es, and Vs, are some of my favorite. The ones that retained the middle cooling fan look like as built GP30’s and 35’s. I set my personal career speed record on the BNSF 2826 (CB&Q 955) at 72mph (woo hoo!)on a geometry test train. Form my money the BNSF has the best diesel roster of the Class 1’s. I mean come on, who else has a Beep!
