Preface
Winton Brown founded the Winton Locomotive Works Company in Danville, California in the early 1960's. Winton was a mechanical engineer by trade. He brought as set of finely honed engineering skills to the company, designing his locomotives for maximum strength, maximum weight on the drivers and easy, modular construction.
The Winton catalog included a section simply entitled “Engineering Notes”. Behind that humble title lay 17 pages of notes, drawings, formulas and tables essential for designing and building model steam locomotives. In the 1960's, if you were building a loco from scratch which wasn't adaptable from a Little Engines design the Winton catalog engineering section was considered the bible and many used it to design parts of their locos, especially boilers.
Winton's engineering data is just as valuable today. It offers, among other things, tips on improving the performance of practically any steam locomotive. An additional article, written by Winton which originally appeared in the Nov/Dec 1954 edition of “The Model Locomotive”, is included in this publication. It points out the importance of superheated steam and works through an example to compute the ratio of water to steam to maintain maximum operational capacity.
Kenneth Shattock, IBLS secretary of the North American Region, encouraged the creation of this document. He realized the importance of preserving this important asset for the live steam community, and increasing its general availability.
The data has been checked against modern standards and updated as needed. Additional helpful tables have also been included. Other modifications have been made to aid the reader in understanding the concepts described by Winton.
