I have two of the these and they run great. My only gripe is no traction tires. If they had them, They would pull like a beast.
I found that it will pull 8 MTL pass. cars up a 1% grade through an s-curve with no wheel slip. I saw a youtube video where it pulled the new Kato 13 car 20th Century Limited on flat level track.
As for the sound, it's off the charts!

Thanks again for all the info.
By the way, My system is a NCE Power Cab.
I'm feeling better already.

Thanks for the help.
I have one other question. Do I need a programming track booster to set the CV'S with this decoder?
I do not use decoder pro.

Hi all,
I'm new to the board. The questions I have.
Has anyone installed a Soundtraxx TSU-750 decoder in the new EM1 steamer.
Do I cut off the old decoder or leave it in place? Also, do I need the capacitor?

Thanks,

Gregg
