Jack,
You are correct about the covers which were not part of the EMD application,
but rather a RR added modification. I don't know about incidences on the Q, but
the Duluth Missabe & Iron Range had two SD-9s equipped with steam generators
that were used to pulled special passenger trains such as Board of Directors
trains. Such trips occurred infrequently. Every time the shop would set up the
units for passenger service, they would find the exhaust stack full of sand. It
wasn't easy getting the sand out once it was in the steam generator. The Q
covers may have been set up on legs so that the exhaust could vent around the
side of the covers. A close up photo might determine whether they were fixed in
place or had to be removed for steam generator use.
