I believe the translation is that these are new "SL Fuyu no Shitsugen Tancho Car" Coaches seen in this latest Suzukawa Video. The C-11-171 has a Plarail version but wouldn't it be neat if Plarail released a 3 Pack of these new Coaches? I woud even be for a release of 2 Coaches with this C-11 just to get the coaches. I love collecting the Plarail Coaches. 
On a separate note: This is the first video I have seen with Suzukawa alone without her camera person husband or her children.
