In response to my original post on this subject, Rich Hunn posted, "In the last few years the next (or that) day helper would switch Skyline
and block the outbouhd lumber. By then the Chama empties would be on the back of the westbound and set over by the inbound helper. This would have
been the years after the Gramps shipments which as I remember we handled
ie switched by a Chama switch job who also handled Skyline."
So the plot thickens. When the tanks were running to Chama, they were on the headend. Logically the other Chama empties would be head end, but we don't know for sure. When the tanks stopped running apparently the Chama empties went on the rear.
Rich's comment about a "Chama switch job" raises all kinds of new questions in my mind. Not only about the switch job itself, but also about the work rules. What craft "owned" the work within the Chama yard limits, since it was a terminal.
No detail is too trivial when it is narrow gauge!
