¦ Version with long sun roof ¦ Finely detailed design with authentic "Transfesa" lettering
Pressurized gas tank wagons are special wagons for liquefied, deep-frozen liquefied or dissolved gases. Loading and unloading takes place using devices that can be operated from the ground (bottom emptying). The eye-catching, approx. 30 cm high, orange vertical stripe in the middle of the boiler is typical of European cars.
For a long time these wagons drove exclusively as private wagons [P] that were registered with the national railway administrations. In contrast to other types of wagons, they are now owned by specialized wagon rental companies. The complex management includes the maintenance, inspection, etc., of the vehicle fleet.
