Kitbashing Santa Fe mechanical refrigerator cars
Part II: Detailing the Rr-87, Rr-90 and Rr-91 refrigerator cars/Jim Providenza L
ast month we reviewed some prototype and model history and covered the basic kitbashing or
scratchbuilding of the carbodies for three HO scale Santa Fe Mechanical Temperature Control refrigerator cars, the Rr-87, Rr-90 and Rr-91. This month we will finish the project with work on the refrigeration equipment vents, the underframes and adding the final de- tails, paint, decals and weathering.
Rr-91 refrigeration vents Let’s start with the vents for the re- frigeration units on the Rr-91. The in- side edges of the door cut-outs on the A-end, left side were framed with HO scale 1″×2″ strip styrene set flush with the inside surface of the car sides, then a piece of Clover House No. 787 60-mesh screen was cut to fit inside this frame. Using a toothpick I placed a thin line of Walthers Goo on the inside of these 1″×2″’s and secured the screen in place. (Refer to the photographs on page 69 of the May issue for more de- tail on this vent and the one described

The author’s Santa Cruz Northern moves a lot of perishables from Northern California growers and packers like U.S. Cold Storage (top). The vents on the A-end, left side of the kitbashed AT&SF Rr-91 are shown next to the original Athearn PFE R70-20 above.
immediately below.)
The vent on the right side was a lit- tle more involved. I first cut a piece of
.005″ styrene sheet 9′-6″ tall by 3′-6″ wide. The screened opening in this plate is 5′-0″ by 2′-3″ with its left edge
