Hi Steve.

Yea pretty much everything here is Sharfenburgers now. That pic was from a Class 313 (now deceased, thank Gawd). They were so old that they had an air-drven cam shaft which switched around the resistance windings. When you pulled the handle you could hear it go "clankety-clank" a dozen times under the train.

In fact that used to be one of the favourite questions for know-it-all trainees. "Which of the following traction types have cam shafts? Steam, Diesel, Electric."

And of course they'd miss out the electric.

Laters.....John.
