I was trying to get a good picture of the bridge abutments on the original Atlantic & Pacific alignment just east of Rio Puerco. While trying to get a good angle on the old structure, this empty coal train came by. It is headed back to the PRB after delivering coal to one of the power plants down the Coronado Sub in eastern Arizona. It turned left at Dalies just up the hill and went over Raton Pass to Trinidad.
I got a better picture of the bridge abutment the next morning. You can see the current double track mainline just beyond the old alignment. The rails were removed from this segment in 1913. Portions of NM 6 were built on top of the old right of way the following year. NM 6 was the origianl designation for this highway that ran all the way to the Arizona border. It became US 66 in 1925. The road from Los Lunas to just west of Suwanee reverted back to NM 6 when US 66 was extended due west out of Albuquerque in 1936.
