Action shots from Amtrak's NB Texas Eagle with the Phase II heritage unit, 66.
These little signals were installed as
part of the High Speed upgrade for this line, as before there was
nothing protecting this sidewalk, and in fact there was another
sidewalk crossing about 100 feet south of this one (about where I was
standing in Picture 3 and seen in this video from 2012) which closed when the signals were installed at this one.
