In the Swiss classification system for railway locomotives, the number of powered axles are followed by the total number of axles separated by a slash. In the case of locomotives with both powered and unpowered axles, no indication is made of how they are laid out. For instance, a 0-8-4, 2-8-2 or 4-8-0 would be referred to as 4/6 despite the fact that their actual wheel arrangements are different.

[edit] Steam, electric and diesel

The first column is the Whyte notation, with the Swiss equivalent to the right.

0-6-0 becomes 3/3

4-6-2 becomes 3/6

2-6-4 becomes 3/6

2-8-0 becomes 4/5

2-6-6-2 became 2x3/5 or 3/5+3/5 up to the early 1920's, later 6/8

[edit] Electric and diesel, all axles driven

Bo-Bo becomes 4/4

Co-Co becomes 6/6
