This passenger car has a special relevance: It was used in the Seventies mainly as a kind of caboose in freight trains on the Pinzgau Railroad. Brakemen and other railroad workers could thus ride along in some comfort and quickly reach their posts. At that time various types of cars were used in freight service on narrow-gauge railroads, among other things boxcars and gondolas but also stake cars for transporting bulky freight. Standard gauge freight cars were also loaded on roller cars and transported on narrow-gauge routes. This meant transloading freight from standard gauge to narrow-gauge freight cars could be avoided and operations could be made considerably more rational.
