Zelko's nursery project was created in cooperation with ŽSR and nonprofit organization LAVAS. It focuses on the education of children in traffic education, safety, prevention and protection of human health and life in connection with traveling by trains and behavior on and near the railway tracks. It is primarily intended for children under school age. The main purpose of the project in addition to the book is an animated documentary, which firstly aims at warning children in appropriate way about the dangers and possible consequences of their careless actions if they do not respect the regulations and prohibitions on the track and in the train. Secondly, it gives instructions on how to behave when traveling by train. The book and first three of ten parts were donated to every kindergarten in Slovakia at the end of 2013.
