Well the BN GP30's and 35's are really GP39M's E's and V's. They were rebuilt by EMD, Morrison Knudson, and VMV. Since they were rebuilt in 88-90 I think they will be around for some time to come. During this rebuilding program retired 30's and 35's were acquired with lineage from SP, SSW, C&EI, GM&O, SOU, N&W,UP and others to name a few. The Santa Fe also rebuilt theirs as well but did the work themselves. For the most part they look like what they did before rebuilding but some of the BN rebuilds have the small middle radiator fan removed is the most noticeable spotting difference. The ex N&W and SOU units were high hood and have a standard cab like a 35 on a GP30, they look kind of goofy to me. I see them quite frequently out here in the Pacific Northwest, we see the old Santa Fe units once in a while. The BN photo archives is an excellent source of info on these units. We dont have any SD-7's left. We have a few GP10's which are rebuilt GP-7's and look alot like one aside from the chopped nose, but the GN had a couple chop nose GP-7's before the merger anyway. The 1410 rolled through town this last spring looking fine. As for the GP-9's and SD'9's it is anybodys guess how long they will be around. I think they retire them as they suffer major component failures. Last fall they sold four SD-9'S to the Port of Tillamook Bay Railroad. But in a pinch for power they wind up on the main line from time to time. In the January issue of CTC Board they reported about four manifest trains headed by solid consists of SD-9's, one which was a little over 12,000 tons with four SD-9's on the point! I was on a work train waiting for a South man to pass and his second unit was SD-9 6136, it was on a M-PASBAR, a pretty heavy train so needless to say it was earning its keep. I think the management may get a notion to rebuild them because they keep equipping turbo-charged motors with the remote control equippment and I think they will run into problems in the future with them. Anyways working for the BNSF I see firsthand the oddball consists and it is great. I am working in the yard now the last road train I worked was a month ago and it was a solid consist of SD40-2's, not a big deal to most but I like it alot better than the SD70M's and AC44TCE's and stuff my neighbor the U.P. runs. Oh yeah I'd rather ride in one of them than a pumkin any day.
