A phrase used by railfans to designate when the headlights of an approaching train are visible glinting off the railroad tracks ahead of the train around a corner, usually before the train itself is visible.

Strictly, it is a “quiet on the set”, as the headlight glint warns of an approaching train and allows a few seconds for background noise to be minimized for when the train actually appears. This provides railroad enthusiasts with pristine sound in their videos of the passing train.

Pragmatically, it is a way for dorky train nerds to dorkily tell other dorky train nerds “ooh, a twain is coming!”
Railfan; “Hot Rail!”

Pause.

Train: “Choo choo!”
