Some four years have elapsed since the second edition of this pamphlet was exhausted. During this period I have constructed and equipped at Eaton Hall, Cheshire, a line which has been in regular use since May, 1896, exactly similar to my own at Duffield. This railway having been made wholly for practical purposes and on strictly economic principles, I am in a position to present more reliable data, both in regard to cost and working, than I could obtain from my own experimental line, which has been continually altered and only irregularly worked.

I desire to take this opportunity of expressing my thanks to the Duke of Westminster for the free hand accorded me in regard to the arrangement of all details of the Eaton Railway; a liberty which has resulted in a symmetrical and entirely successful carrying out of the work.

What I am now able to advance will, I trust, amply demonstrate the really solid advantages which, under suitable conditions, may be reaped from the installation of little railways of the kind described.
