Locomotive Inspection Act
The Federal Boiler Inspection Act, also called the Railroad Inspection Act,  expanded the Boiler Inspection Act of 1911 to include federal interstate commerce clause regulation not just of train engine boilers, but of the entire train as well as cargo to ensure safety for workers and passengers. In 1915 the Boiler Inspection Act was expanded and retitled to the Locomotive Inspection Act. Notes
