G'day John and Philip,
Thanks for the Deltic info.
Yes, I can now see that the drive shafts are actually to do with radiator fans rotation.
Via the usual clutch, Eddy Current clutch as we calls such here, though that was the patent name specific to Alco.
We also refer to the Supercharger as a Turbo.
EMD and other two stroke donk manufacturers tended to refer to the dingus as a supercharger.
Oh, and John you ain't been inside the engineroom of an MKA rebuilt CLP class AT26HC-2M.
Not only the racket from the EMD 645E3C, but also the HEP generator.
Hideous things, thankfully were acquired by our opposition after privatization.
Only had to work one twice when called out to fire on the Silver Streak in the late 1990s.
They were very unreliable, compared to the original Clyde built CL class prior to being bashed by MKA.
And, the loco handbrake was inside the engineroom.
So, had to trudge in there to crank on the handbrake after stabling the train at Central station.
Crew were required to wear ear protection when being inside the mongrel things.
Steve.
