As described by the NGS in 1973 (although already monumented by the CGS back in 1932):
"[...] 103 FEET SOUTH OF A POWER POLE SUPPORTING 3 TRANSFORMERS (NO. 13481), 53 FEET WEST OF THE CENTER LINE OF A GRAVEL ROAD, 45 FEET EAST OF THE EAST RAIL, 1.2 FEET NORTH OF A METAL WITNESS POST, AND ABOUT 1 FOOT BELOW THE LEVEL OF THE RAIL, SET IN THE TOP OF A CONCRETE POST PROJECTING 0.2 FOOT."
Save for the mention of the "GRAVEL ROAD" (it's now paved, and called "Old Hardy Road"), the NGS description is still pretty accurate, and so are the distance estimates from the rail tracks and the street... The witness post is still there as well.
The NGS' currently posted coordinates ("N 30 10 56.76 W 095 26 33.18") seemed reasonably accurate: my measurements were "N 30° 10.946 W 095° 26.555" based on 10+ readings within 10' accuracy.
The station was recovered in good condition.
