Just like the reverser reach rods had a universal joint located just above the pivot point at the rear of the engine. Travel there is very minimal. N&W steam power used

Okadee valves that where air operated .  I believe 611 got the steam Cylinder cocks during the rebuild in 82

Subject: Cylinder Cocks on Mallets ?


One thing I never figured out while we still had steam... 


How are cylinder cocks handled on articulated engines?  On single engines, the cylinder cocks were actived by a single reach rod. 


But how were the cylinder cocks activated on Mallets?   Was it done pneumatically, from a single globe valve in the cab?
