20: This model of PFE Class R-40-23 is an InterMountain
ready-to-run car. It models a repaint, using the paint
scheme introduced in 1951, though all side hardware
should be orange. The UP emblem is black and white,
and the SP emblem is toward the B end of the car on
both sides, thus making the two sides non-identical. In
the background, another reefer is about to be spotted at
the ice house in my layout town of Shumala.

During 1937-1942, for example, about 19,000 cars were
washed each year. So age alone cannot determine how dirty a
PFE car ought to be, see (18) and (19).
PFE classes
Now let’s look at how some of these classes can be modeled –
some have multiple possibilities. I begin with the larger classes.
Class R-40-23.
This was PFE’s largest class of new (as op-
posed to rebuilt) cars, and as Table 2 shows, was divided into
two number series, 5001-8000 and 46703-48702, totaling 5000
cars when new. The best and most accurate model in HO scale
