Selection of Papers by L.D. Porta – Volume 1

Triblogy and Lubrication

[undergoing proof checking – not yet available for sale]

The Argentinean engineer Livio Danre Porta (1922 – 2003) remains an unsung hero in the long history of steam development. Following in the footsteps of Chapelon, he rebuilt numerous locomotives in Argentina and elsewhere, and designed several revolutionary locomotives, both large and small. Like Chapelon, none of his designs were built and most of his rebuilds have been lost to the scrap merchants. He has however left a rich legacy in the form of several hundred technical papers covering a wide range of subjects and written in a variety of languages. A few of his papers were published in conference proceedings and some were left in typed format, but the majority were left as hand-written manuscripts.  Some were written for specific purposes such as his “A1 Paper” that was written in the hope of influencing the design of Tornado, and his “Compounding” paper that was written to try to influence David Wardale’s design of the 5AT. Others were written for the purpose of ensuring that the development of steam locomotives would continue into the 21st century.  The papers that are left to us are mostly of poor quality, having been photocopied many times and circulated amongst the “modern steam aficionados”. These can be hard to read, and most contain “Porta-isms” (grammatical errors) that require interpretation.

Chris Newman has transcribed 19 of Porta’s English-language papers and is publishing them in three volumes through the auspices of the Advanced Steam Traction Trust and with the permission of the Porta Family Foundation. This first volume offers a trilogy of papers relating to tribology and lubrication, subjects of especial interest to him and which should be of special interest to the 21st century steam community. It is hoped that much will be learned from them.

This volume titled “Triboligy and Lubrication” includes five papers as follows:

  • Steam Engine Cylinder Tribology 1975 edition
  • 1975 Tribology Paper Sections 6-14
  • Steam Engine Cylinder Tribology 1995 edition
  • Cooling of Piston Valve Liners
  • Mechanical Design of Piston Valves.

Covering 240 black in white A4 pages, this volume is expected to be priced in the region of £25.
