The US government updated its address for steam locomotive inspections

The US Federal Railroad Administration made minor administrative changes to its rules for inspecting and maintaining steam locomotives. This means the agency's contact information in the regulations is now correct.

This document is a reminder that even the most niche and seemingly obsolete technologies still require active regulatory oversight. The rules for steam locomotives, a technology largely replaced by diesel in the 1950s, still need to be maintained and updated. It shows the long tail of infrastructure and regulatory inertia.
