I spotted 72-91 004 in Metropol on 23rd Dec 2015:

Not only Najbrt-colour scheme but also bears the new "Národní dopravce" slogan under the logo.
The 61 54 72-91 004-6 (ex "Lednice-Valtice") is the only WLABmz 826 in new colours (since 11/2015).
In which trains can it currently be seen? Does anyone have more photos or revision dates of this sleeping-car?
Thanks, tobias
