I thought it was a little odd that Lionel is offering Berkshires for sale in S and is not marketing matching cabooses in S (or is it Cabeese?)
I know that in S Lionel sold an Chessie System Caboose in 1980 and 2007, Southern Cabooses in 1984 & 2005 , a NKP Caboose in 1997, an Erie Caboose in 2006 and only American Models ever made a Pere Marquette and it is currently out of stock.
With the matching cabeese in S made between 9 to 35 years before the expected release date of these engines in S and one NEVER made in S by Lionel, one might think that producing matching cabooses in S would be a "no brainer". However, as I have said before, on other threads, I have NO idea what Lionel is doing with AF.
