The description for this classic photograph suggests this train is the Houston and Texas Central's version of the Dallas Morning News train called the "Comet." It's not!

It's actually the T&P Dallas Morning News train. H&TC had no locomotive No. 95. The script lettering on the engineer's side spells out Texas & Pacific. There's a T&P diamond on the headlight. Finally the eagle on one of the domes is a typical T&P touch.
