From what I understand, there were only two track additions made to Farmington to deal with the pipe and gas field traffic. A long siding was built out side of town where El Paso Natural Gas had its pipe yard. This track could hold a train length of pipe. The other addition was an extension of a siding in the yard by the water tank and depot. The big issue in Farmington was all the cars of drill mud and other supplies. There was simply not enough track space for all the cars. They were using the wye as a team track. The yard would be full of unloaded cars when the next train came in. Crews would sit around and wait for cars to be unloaded, just so they could move them and put more loads in their place.
The long pipe siding was also a problem with switching. Frequently, they would nose into the siding and couple into all the empty pipe gons and idlers, and shove them ahead as they brought the train in behind them, leaving the caboose on the main. With the pipe on the rear, the would cut it off and go back and pick up the caboose. Now, with the big cut empties on the front of the engine, and all the boxcars of drill mud behind them, they head off into town as there was no place to leave the empty pipe/idlers. In the downtown yard, they had to figure out where to stash all the empties before they pulled empty boxcars and spotted loaded ones. All in a way-to-small yard. They easily spent 10 hours switching/sitting in Farmington on each trip, plus 2.5 hours each way in running time.
