Athearn Genesis MT4 2024 Review Part 2. Slow speed performance. 

Nice. I just ordered the same model; I've been wanting a steam locomotive and this is the one. I hope it runs well on my layout. Did you use JMRI Decoder Pro to adjust the CV's? Would you mind sharing the changes you made? Thanks for the reviews, they convinced me to buy this model.

You should be able to get it to run slower by making sure the value for CV 215 matches your track voltage.

Cool you did the horn. How about you actually do the whistle?
