Chuff on Y6b

Should  the chuff on a Y6B be 4-6 or 8? 

Dave

Since the N&W Y Class locomotives are compound articulated steam locomotives, they start in "simple", i.e. 8 chuffs per revolution, then automatically change to "compound" with only 4 chuffs per revolution throughout the rest of their speed range.

Thanks Hot, that's what I thought but that's kind of tough to replicate in a model with sound. 

Any thoughts on how that could be done If even possible?

Dave

MTH does it well.

Thanks Chris but I can't hear the difference. Must be more pronounced in person.

The change does not happen until very near the end of the video.

I can always depend on my buddy for a wise crack although being hard of hearing does have its advantages.

I'm sure you'll get me back soon enough! 

To be honest, I can't hear it on the clip in this post either - probably because I'm on using my phone at the moment.

You can easily hear it on the Lionel Y6b from the last production and I have one and Iris great.

The MTH Y6b models do NOT change from "simple" to "compound", as does the later production of the Lionel N&W Y6b models.

I have the Lionel Y6b, and the change is very clear, I think around speed step 25 on the Legacy CAB2 as I recall.  The Legacy locomotive is a very nice piece!
