A nice find! This is the set that now operates the hump. SD40-2's #1790 and #1670 sandwich #302, an SD40-2B. As of 2012, only three SD40-2B's operate on the BNSF system, #300 - 302. All three can only be found in Galesburg. #302 has the distinction of having its dynamic brakes remounted over the former cab area.
