5AT FDC Publication Front Cover

Thank you for your interest in purchasing a printed copy of David Wardale's "Fundamental Design Calculations" for the 5AT Locomotive. The book, described in the Review pages of this website, consists of 556 page A4 "perfect bound" (soft-cover) pages containing over 6,500 lines of design calculations and 102 diagrams.

The calculations are published at the specific request of David Wardale who wants his work to be made available to anyone wishing to put them to use and/or to those wishing to become familiar with Porta’s design methodology.  Wardale sees the published FDCs as a companion volume to his book "The Red Devil and Other Tales from the Age of Steam" in that together they combine virtually all of his knowledge and experience relating to steam locomotive engineering.

Important Notes:

  1. All proceeds from the sale of the book will accrue to Advanced Steam Traction Services Ltd. (ASTS), and will be used to fund its work improving the performance, reliability and/or economy of steam locomotives.
  2. Since no royalties or other commissions are being paid from books sold directly by ASTS, and since ASTS has few overheads and no paid staff, you can be reassured that almost 100% of proceeds from the book will be put to good use.
  3. Because of unpredictable demand, this book is being printed in small batches of 20 or 30 copies.  As a result, there may sometimes be a short delay in delivery following placement of an order.
