Dano99a,

Can you tell me your settings?  It may not apply with my NCE system, but I tried setting the accleration and deceleration at various settings and it still occurs.  When it restarts after loosing power it jumps to a higher speed while the chuff starts over.

I may modify the installation to additional tender wheel pickup as suggested above, but hate to cut into the harness to get the pickups to the decoder.

I have the same locomotive and the same problem. Here's how I fixed it:

1. Cleaned my track. Then adjusted the acceleration and deceleration rate, so that when it hits a dead spot it will start back up slowly and then come up to speed and the sound will match.

or you can do:

2.install a cam as this will ultimately set the steam chuff to match the rotation of the wheel

Maybe programming in some momentum would help.

The above is my opinion, from an active and experienced Model Railroader in N scale and HO since 1961.

Problem with Tsunami in an Athearn 2-8-2
Posted by GMILL47 on Thursday, September 29, 2011 10:24 PM

I have a Tsunami in an Athearn Mikado and when it loses power, it restarts at the speed it was going (or so it seems) but the sound chuff restarts at slow speed.  Is there a way to get it to restart slowly - perhaps a CV setting?  I have tried resetting to factory defaults but that doesn't help.  And, I know, if I fix it so it doesn't lose contact, I won't have the problem.  Well, I'm making improvents, but when it stops due to a momentary loss of contact and restarts, it jum[ps rather than start slowly.  Suggestions?
