3/16 scale boxcars and reefers. Not many reefers were done, so they can be a challenge to find.
FYI, as I do this series, these are my loose items, ie, not in a set. There are some cars that were available, but will not show up until I do sets. A good example will be PRR boxcars, none here, but plenty of them in sets and with varying road numbers.
