Bill,

Thanks much for responding.

I'm modeling 9935A and 9935B (the numbers Walthers chose) with the red nose stripes.

Here's a shot of 9935A without the doghouse--presumably at a time previous to my period of interest.

Here's a shot of 9935A WITH the doghouse (only one):

You can see the trailing unit also has only one doghouse.  For my purposes, I'm going to assume it's 9935B.  Perhaps incorrectly.  But there are/were at least these two E's that had only one doghouse.

With only one doghouse, compared to the two of many of the other E7's, it seems likely that there would have only been half as many steam generators:  one.  I find that interesting.

Your suggestion that the doghouse is to minimize over-pressure exhaust steam problems is also interesting.  But then, why aren't the doghouses on other units?  The E8's and E9's?


Thanks,

Ed
