The Federal regulations that govern the operation of steam locomotives in the United States requires that periodic inspections be performed. These inspections are performed to ensure potential safety issues are revealed in a timely manner and any issues found are mitigated before the locomotive can be operated. One of the tests required is the hydrostatic test of the boiler at a pressure in excess of the maximum allowed working pressure of the locomotive. These images were made during a recent hydrostatic test of the VC-2.
