This work by Ralph Pütz provides a comprehensive overview of the current developments in modern bus technology. It is particularly suitable for the qualification of participants in vocational training and students of vehicle engineering – serving both as foundational reading and as a technical compendium. It summarizes the fundamental vehicle technology knowledge related to buses and serves as an adequate compendium for participants in the BOKraft operations manager training offered by VDV-Akademie GmbH. For those already appointed as BOKraft operations managers who do not wish to undergo further training, it offers the opportunity for self-directed learning if they are interested. The increased emphasis on the area of drive technology, particularly regarding environmental performance, reflects its significance in public discourse.
