I have a very specific piece of maintenance for model refrigerator cars to mention today, namely ice hatch latches. These are very visible on a model, being located on the roof, so missing latches are quite evident, and of course should not be missing. But their location also means that they are quite vulnerable to being brushed or knocked off and lost in the weeds. So something like the view below, showing my model of PFE 64739, is not what we want. (You can click to enlarge if you wish.)
Replacement latches may be found in extra parts sprues from previous kit builds, though these are often rather too big, especially in thickness. A far better solution is the etched stainless steel latches from Plano Model Products, their part number 12079 in HO scale. The fret is shown below. Obviously there are six sets of four. These may not match the latches of every reefer owner, but they suit my PFE cars.
I pre-paint these, usually some variation of boxcar red, since most of my reefers have that color roof and ends. I usually cut them from the sprue with a hobby knife, then I apply these nice latches with canopy glue. Here they are attached to PFE 64739. This model is built from Sunshine parts, given to me by Frank Hodina, and assembled with the high hatch coamings sometimes seen on rebuilt cars.
These latches can also enhance models of somewhat lower detail level. Years ago I posted a description of the efforts I’ve made to upgrade Athearn steel reefer models, particularly removing the gross “hinges” on the ice hatches (see that post at: https://modelingthesp.blogspot.com/2012/08/ujpgrading-old-models-athearn-reefers.html ).
The Athearn ice hatch latches are also considerably oversize, so replacing them with the Plano parts is a definite improvement. Note also below that I have replaced the kit running board with etched metal, replaced the Athearn brake wheel, and added wire grab irons, placard board, and fan shaft, along with decal re-lettering.
I continue to need to replace latch bars that have been knocked off of reefer models in operating sessions, so I expect to keep on needing those Plano 12079 sets. Appearance of this detail part speaks for itself.
