The pocket book is a private edition of Railwaytraining.

It was compiled on the basis of the GCU, appendix 9 and was further supplemented with some RID rules.
It is also linked to the wagon inspector manual, where the same structure of the pocket book was used.

There was deliberately no other info included to keep the pocket book clear.
The printed version was printed on polyester "paper" so that it can easily withstand weather and wind.

A new version is published every year.
