The present volume sums up 200 problems contained in four chapters, which are essentially problems of dynamics and applications specific to railways. These problems are the result of an experience acquired during the last 20 years, an experience that started on the school benches and continued until now, as an object of daily activities in the field of railway transport, a phenomenon in which I participated directly or tangentially, both objectively and and subjective, de jure and/or de facto.
