The FS Class 623 were a class of 2-6-0 "Mogul" type steam locomotives used on the FS, Italian State Railways.
In the early 1950s a total of 35 class 625 locomotives, of which ten were ex-Class 600 rebuilds, were rebuilt into the class 623.
The design was not successful, and these engines were all withdrawn by the early 1970s, with none surviving into preservation.
Trivia[]
- Fitted with the Franco-Crosti boiler (with two pre-heaters placed on the sides of the boiler), these engines were visually distinctive.
