The BNSF 'Buck Local' operates between Longmont, CO and Denver 6 days a week. With GEVO Power on the point, the 'Buck' is seen arriving back in Longmont before pulling into the East yard.
A pair of ex-Santa Fe EMD SD40-2's, one in the original paint scheme, the other re-painted to the H1 BNSF scheme, are currently in service on the BNSF Longmont Turn.
