Title: Steam Cuff Rate
Post by: Mrpicks on March 02, 2025, 01:25:59 PM

Is there a Tutorial on setting the chuff rate on Steam Locomotives?

I believe the standard is 4 chuffs for each full rotation of the drivers. You may have to set each locomotive differently depending upon the diameter of the wheels.

Thank you Al for your reply. Was away several days and not able to respond.

Somewhere (on this board I think) Is an involved tutorial on setting the speed curve. That was supposed to help get the Chuff Rate close, but it was never perfect.  What scale are you?  If using the "G" module, you can trigger chuff with a reed switch and a magnet, or a locos built in chuff switch. It's still not perfect, but once you learn how to "play" the speed when accelerating and decelerating, it's pretty good.
