The book clearly shows the complex process of development of the uniform from the beginning of the Peter's transformations to the end of the 20th century. And this gives a unique opportunity to trace in great detail how certain historical events were reflected on the uniform. In this book, for the first time, the most extensive historical and archival material about the uniforms of railway workers was systematized and summarized - the history and description of uniforms, regalia and insignia of posts, services and units.
