MODELING THE GEEPS ...

This month's column is the first in a series about modeling the C&O Geep fleet. Don't worry - I'm not going to do another marathon set like the wooden water tanks for a while! I'll present prototype data this month, then at random intervals over the next year or so model a specific engine.

Keep in mind that the following spotting features were for the units as built, and that the further away in time one goes the more changes were done. A couple of publications I found to be invaluable in tabulating this data were the C&O Diesel Data book, the "Phases at a Glance" series by Mainline Modeler, and Extra 2200 South 's C&O roster.

AS-BUILT C&O GEEP SPOTTING FEATURES

GP7 Phase I:

Sloping sheet metal boxes on the pilot steps

Cast buffer

Louver groups under cab (both sides)

2 louver panels on doors 2, 10, and 13

1 louver panel on door 1 in upper position

All fans 36" dia. (Including D.B.)

Long hood doors 86" high

Solid fuel tank skirt (an exception to this appears to be the

Canadian-built units which have a single long slot.)

GP7 Phase II:

MU hose boxes on the pilot steps

Dynamic brake fan increased to 48" after 7-52

Long hood doors shortened to 82" high after 3-52

Inspection holes in fuel tank skirt

No changes in louvers

GP7 Phase III and GP9 Phase I:

Louvers under cab disappear (still on battery box doors)

Fabricated buffer

2 louver groups added to door 4

1 louver group added to door 1 in lower position

Lower louver group deleted from door 13

GP9 Phase II:

2 louver groups added to door 5

Fuel filler moved forward on units built from 2-57

GP9 Phase III:

Large louver group on battery box door is changed to a small pair of louvers at top of the door

Fuel tank skirt cut away except around fuel filler

Fans changed to 48" diameter "pan" top fans in 10-57

Doors 1 and 2 have lower louver group removed
