Athearn/MDC has the unchopped version of this car in several PFE variants:

What was included in the Mocalova kit?  I'm not familiar with that (and I gather it's not still available).

So what is the advantage of the chopped version?  Better airflow for the refrigerator unit?

1969 apparently.
If they do them up in PFE I'm in for one!

You're talking about the original cars, not the conversions.
Not saying IMRC won't do them, but it would be additional tooling, as these have a big hole in the roof. (and sides)

IMRC is going to release the as-built version also, but they are releasing the model of the converted car first.

My wild arse guesses:
-Yes, airflow was more important for the higher efficiency unit
-Using the standard carrier form factor probably meant cutting the car in some manner anyway.
-The Carrier Ultima units have GPS and removing part of the roof was more cost effective (and durable) than a GPS dome on top
-Opening things up made for easier maintenance
-Anti-theft features in the Ultima units meant that theft was an acceptible risk proposition given the benefits of opening things up.

I found some unconfirmed info that BNSF did 76 conversions, while UP had almost 3500.  They weren't all the same class though....not sure how many R-70-20's we're talking about.

I might be interested in finishing that!

You're on Tom!  Here is where it stands now:




[The reefer unit slides in after painting.]  It's actually not as bad as I remembered. The only problem is the current white isn't quite opaque enough and it's dead flat.  If you can manage a very thin coat of gloss white, it probably wouldn't need stripping.  PM me and we can make arrangements.  All I ask is that you post pictures of your results.  :)

Gary

Where did you get that awesome ac unit.I love it

Heath, the reefer unit is a Fine N Scale resin casting from this set.  I just mounted it on a styrene wall and added a bit of wire "piping".  The other bits that went into this were some BLMA ladders and K&S etched screen stock.

Thanks Lou.  It turned out well up to the paint job.  Tom is going to inherit it now and rescue it from oblivion.  ;)
