This was a rather unusual operation so I have created a separate gallery to document it.  In the last years of the Rio Grande ng. the line was closed during the winter to save on snow clearing costs over 10,000 foot Cumbres pass.  Following the Silverton season of 1967 the 476 and 478 were sent to Alamosa for shop work during the winter.  By May of 1968 they were needed in Durango for the Silverton season, so on May 28, 1968 they pulled the first train following the winter closure from Alamosa to Durango. Doubleheaded K-28's were rare on freights, especially with the fake diamond stacks for the Silverton    It was a relatively short train, so there was no need to cut the helper into the train from Antonio to Cumbres as was more  typical.  And they ran the 200 miles from Alamosa to Durango in a single (long) day instead of making the usual overnight stop at Chama.  The train left Alamosa just after sunrise and arrived at Durango around 11 p.m. that night.  It was the first train of the last season of DRGW ng. freight operations, with the last revenue freight operation the following August and the final "cleanup" trains in December.
