These cars were hard to find (even on ebay), but unknown to me Kato planned a limited run late last year. Looks like they must’ve just shipped them to dealers. I saw them on the new arrivals lists at modeltrainstuff.com. They only had 16 of each set in stock, so I ordered one of each before I lost my chance. I want to use these cars with the UP Big Boy.

So if you’re looking for these cars, head over the MTS(Set A, Set B), your favorite online dealer or local hobby shop before they’re gone again.
