The boiler is effectively stripped down now. All the jacketing, piping, and insulation have been removed from the exterior, and all the tubes have been removed from the interior in preparation for inspection and testing.
Eric Wunz ultrasound testing (UT) the thickness of the firebox sheets.
Jerry Huck recording the UT information so that a new complete grid will be available on number 19. By comparing previous UT measurements with these new ones it is possible to determine which areas of the boiler showed thinning or other problems.
Boiler interior on number 19 looking forward towards the smokebox. Overhead is the drypipe which directs steam to the cylinders. The shiny metal is the front tube sheet which supports the boiler tubes.
Number 19 boiler looking back towards the firebox. You can see all the staybolts that hold the firebox in place an allow for water to surround it.
