Stack Extenders for ATSF Steam
Engines
Compiled by J. Stephen Sandifer
Just what are these things and what
do they do.
Three major designs were used, with
at least 2 variations on each. Since I don't know the technical
designation for these, I have taken the liberty of calling them
the Scoop Deflector, the Hinged Can, and the Telescopic Stack.
Some locomotives were delivered without
an extender, then one was added, then it was replace with yet another
design. The 3751 is one of the more famous engines that went through
this evolution utilizing 2 designs over time.
3751 new, in 1938, in 1947
and as retired
This information will challenge the
precise modeler to select his time frame when putting the finishing
touches on his engine.
