In 1913 the Panhandle & Santa Fe railroad acquired a railroad chartered as Pecos River Railroad. It began at Pecos, TX and extended northward to Carlsbad, Artesia, and Roswell, NM. Circa 1990 trackage from Pecos to Loving, NM was abandoned and taken up. The reason I bring this subject up is because that region where the line is gone is now the red-hot epicenter of oil and gas exploration. I would bet a nickel that BNSF wishes they had that trackage back...they would be hauling all oilfield related commodities in staggering numbers.
To add to my store of unessential knowledge, I would like to start a discussion with people who know the various reasons, costs, and advantages of rail line abandonment. On the remainder of the old Pecos Valley, once spun off but reacquired by BNSF, I have seen new construction of large frac sand receiving spurs. The entire region is "on fire" with commodity hauling, and the highway infrastruction is getting beat to a pulp.
I would like to read comments from people who have expertise on this subject.
