Friends, a number of CB&Q steam locomotives were originally
constructed for, or were converted later to use specifically either
Bituminous coal (Illinois), or Lignite (Wyoming?). As I understand
it, Hastings NE was the dividing point in this regard.
Now, just exactly were the specific differences between locomotives
equipped to burn one or the other? I do note in Corbin's book that
some locomotives have the appearance of really marked smoke box
extensions, while others of the same class do not- with no
explanation.
One caption mentions that the bulging smoke box was to provide a
much bigger chamber for unconsumed lignite particles to burn out
before being pushed out the stack. Is this bulging smoke box one of
the features exclusive to lignite, and in this regard, some, or all?
Would an order for new locomotives X number for bituminous, and Y for
lignite then come from the manufacturer with these respective and
distinctive smokebox differences?
