Download the Traction Addendum

Since the 6th edition came out in 2021, we’ve added a new chapter explaining how electric traction works. If you download the full 6th edition here it includes that chapter.

If you previously printed out the 6th edition before we added the new chapter, you can download, print and insert the extra pages in your printed copy. The PDF below includes revised Table of Contents and Table of Figures pages as well as the actual chapter. Note that this has been numbered as Chapter 23 to avoid upsetting your existing page numbering. In the full download it is Chapter 11.
