Camelback throttle

I was curious about how a Camelback loco throttle is mounted. 

 

Thanks.

Just looked at a photo of a 'de-cabbed' camelback.  The throttle appears to have been mounted to the valve operating shaft sticking out of the engineer's side of the steam dome.

The Russian decapods had a similar dome fitting, connected to the throttle in the cab by a reach rod.  Dome throttles with outside linkages were also standard on all later Japanese locomotives.

Thanks for the info.  Any possibility you could share that photo?  Thanks.

Greg, it's the first photo in IMAGES wheen you Google Camelback Locomotive Cab Interior.  The loco is an eight-wheeler (4-4-0) and the engineer's cab is completely missing - probably awaiting restoration, since the loco doesn't appear damaged otherwise.

I think you will find that the throttle works very similar to the following:

Thanks for the illustration BigJim.  Been a bit of a mystery to me for a little while...
