he kangaroo wagons run in block trains of several dozen wagons. They are necessarily all oriented in the same direction, otherwise the loading and unloading operations would be impossible.

However, and this from 1962, new regulations in the highway code, new tractors with short cabins and new measures taken by the
French National Railway Company (SNCF) make this type of wagon outdated! In fact, as the technique evolves, we have:
* a change from for the weight of the road assemblies with as a corollary a weight of the semi-trailer of up to ,
* a change from for the length of road assemblies,
* and the placing on the market of a short tractor, with as a corollary of these two points a length of the semi-trailer which can be up to ,
* an ability to travel at up to on the
courier trains,
* and finally, with a view to the application of the
automatic coupling, a design that can accommodate it.

Thus from 1967 to 1968 a total of 80 wagons built in two series are delivered:

* the 6 series without screw brake for 40 wagons.
