Are these locos no longer availalble?
They are getting very hard to find. Only 81495 and 81496 were still shown in the 2010 catalog. The 2-6-0 81495 (Baldwin Locomotive Works) was still in the catalog in 2011, others may still be found at dealers here and there. If you find one it is probably a good idea to get it while you can. They still show up on Ebay as well.
Forgot to mention there are none listed in the 2012 catalog,
