This is a postal high-speed service based on a modified Sud-Est TGV. it was carrying mail and parcels on the SouthEast high-speed line. This train is gone on a double count. Firstly, postal TGVs have disappeared in June 2015. Next, all Sud-Est TGVs - the first generation high-speed trains in France - were withdrawn in December 2019.
From a hint of "Bee" (NKP 765), colorful "Bees" (KCS), "Bees" w/ attitude, to "Bees" that "sting" your eyes, in their own way they have "Bee" on display! Equipment that "Buzzes" with Yellow & Black colors! ("Bees" can still "Bee" entering this "hive"!)
