Question

When were locomotives first required to have ditch lights?

Answer 1

In December of 1997 any train operating over a grade crossing running over 20 mph had to have ditch lights.But we started getting them on our locomotives in the early 90's

Answer 2

Indeed, I believe December of '97, as Andy stated, was the cut-off date when the FRA mandate went into effect.
