Greenberg's Model Railroading With Marklin Z by Riley O'Connor (1989, Paperback)

This is the only model railroad text which is devoted entirely to Z-Scale trains, the world's smallest electric trains. It was written in the late 1980's and was published in the early 1990's. Although the text is comprehensive on the subject, it is also dated and primarily sought by collectors. Current information can be found on a website located at http://www.guidetozcale.com .
