This section describes the Heisler main frame and tender frame.
The photo above shows probably the most unique frame feature of the "West Coast Special", the cast frame stiffeners mounted between the upper and lower frame bars. These stiffeners have slots to provide access to the boiler stay bolts. That's the mechanical lubricator mounted to the left side stiffener
The frames have been finished:
