Summary

Within 1 year after the Rail Safety Improvement Act of 2008 became law, the Secretary of Transportation must write rules and guidance for developing, using, and putting into service rail safety technology when no federal rules already apply. This includes things like switch position monitors, remote‑control switches, hot‑box/high‑water/earthquake detectors, slide fences, grade‑crossing cameras, track‑integrity alarms, and similar devices. Dark territory means parts of railroad track that do not have a signal or train‑control system installed or working.
