Reply to "Video on how to modify front drivers on a 2-6-6-2...or other Articulated"

A little confused... the 2-6-6-2s are compound engines, the rear cylinders feed the exhausted steam to the front cylinders then out the stack. How would this make any alteration to the sound (if it were even possible for the sound file to account for the out of sync drivers)? Should be 4 chuffs/ rev like a regular steam engine.
Simple articulateds (4 independent cylinders, Challenger, BB, etc...) would drift in and out, but I dont know if the sound file has the ability to adjust. GRJ probably knows if there's a switch or hall sensor on both sets of drivers...

Yep - still true. I made this point on another thread yesterday. I imagine that it will have to be made again.

And the "drifting in and out" is perceptible only at low speeds. Still.
