A very special, unique car, the Xas 383 # 231, based in the maintenance and intervention center Biasca. A big gate, folded like a butterfly, serves to seal the tube during maintenance work in the Gotthard base tunnel, thus sucked bad air in the maintenance area and fresh air can be supplied. The car has automatic couplers, for the quick train formation with other vehicles like the self propelled Xem 181.
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"!)
