Here the Big D&RGW derrick is not being used, but has been positioned near the rear of the big Uintah engine, in preperation of lifting the rear of the locomotive in to the air. It seems that the Erie heavy flat car had a "lowered" center, and #51 was shipped from Baldwin with the drivers down in this? For what ever reason, it was deemed neccissary to hoist the large locomotive into the air and build a section fo track under the loco. This was accomplished by hoisting it into the air, one end at a time, and placing the wieght of the engine on stacks of cribbing in the location of the front and rear trucks (which were not attached). Then with the locomotives driver hanging in the air, the make shift track was built under the loco. Here Master Mechanic Scott Shaffer (with the white jacket standing near the front drivers) is busy tring to watch the front trucks nto get in to a bind. At the rear of the flat car (a small section fo three rail) Uintah engine #12 (ex- Florence & Cripple Creek, only surviving Uintah Loco) sets - supposedly suppling air - for braking on the "Mallet". At the right a group of five school boys have been invited to watch the proceedings, setting on top of a B&B track cart loaded with ties. Notice the pre-made section of track in the foreground between the boys and #51. It looks like extra long timbers have been used for eas of getting a hold and positioning the piece of track under the locomotive ( I imagine that they used the derrick to left the piece of track). After the Locomotive was on flat piece of track on top of the flat car, a small trestle was built behind the flat car and piece of track laid up to the top of the flat car, engine #12 then supplied the air to let the engine back down to track level.
