For 50 years, the LEGO train has not only made children's hearts beat faster - adults are also rediscovering their old LEGO train in the basement or attic. This book shows how even older trains can be operated with the current system and how sophisticated and beautiful train models can be created. An introduction to LEGO building techniques, which is not only applicable to the world of trains and tracks, provides the necessary background knowledge for your own constructions. In this second edition, Holger Matthes presents the potential of the new motor generation Powered Up for building train models. The references to third-party offerings and sources of supply have been updated and expanded. The reader can also look behind the scenes of the construction of a model of the iconic Trans Europ Express. Holger Matthes describes the basic concepts of innovative building with LEGO, but also shows the limitations that LEGO brings to the world of trains. All models and illustrations are impressively shown in color. The book is rounded off by its numerous building instructions for self-building and further development. The reader can thus increase their own creativity with this well-founded reference work and design realistic models themselves. This book is neither supported nor authorized by the LEGO Group.
