The great old Western Maryland Fireball, born in the steam era, never looked as good as it did to me than the day I saw it on 734 with steam swirling about, as the crew readied her for the day's run.
Generally speaking, shots where less than a full engine is shown. But I want to feature details, not half engines or full cabs, and definitely not full nose shots. Just shots where someone has zoomed in with purpose.
