I always thought those were bazookas for use on trucks stalled on grade
crossings.

Although the "torpedo tubes" on top of the long hood was more common in
passenger units for the reason Bob cited, I think they also
sometimes ended up there so the fuel tank under the frame could be enlarged
for longer range operation.
DL&W also had such units, and, I think, IC; probably others that don't come
immediately to mind.

Here's a photo of PRR 8552, the sister engine to the one modeled:

The top features are air reservoirs. Most Geeps have their air tanks located
behind the fuel tank, but in some cases particularly on passenger Geeps, the
space behind the fuel tanks is occupied by the need for an enlarged tank to
accommodate additional capacity for steam boiler water. In this particular
case, the space behind the tank was used for the rectangular box that houses
cab signal equipment.
I model the Pennsy's Elmira Branch in the late '50s. This particular GP-7
spent a lot time roaming the branch duing that time period. In the '60s it was
sent to Chicago and assigned to commuter service.

Bob,
what railroad do you model after. I have not seen any GP-7's with the top
features that you have. What is it.
Thanks,
Alan
If you've been following my posts on the conversion of the AM GP-9 to a
GP-7, I'm happy report that the locomotive coversion is complete and ready to
be moved to the paint shop. I've uploaded a couple of progress photos showing
the pre-painted version, which you can view here:
http://groups.yahoo.com/group/S-Scale/photos/album/2131888790/pic/1430517891/view?picmode=&mode=tn&order=ordinal&start=1&count=20&dir=asc
or, in the "Bob Frascella's GP-7" file on the group website.
It's hard to tell from the photos but all the walking surfaces include the
installation of the Archer treadplate which adds a nice texture to the
otherwise smooth surface. A couple of other items of interest include the
modified AM fuel/water tank. When I compared it to the plans in Mainline
Modeler, I discovered that the fuel tank was not tall enough and rode too high
above the rails. I also added the Pennsy cab signal box behind the fuel tank,
thus the reason for the roof-mounted air tanks. The correct GP-7 early handrail
stanchions were used. These are very delicate castings and bend very easily but
the well worth the effort.
I'll post more photos after painting and decaling.
