TMCC 1

Drilling the larger hole and removing the sleeve seems to improve things for any vintage fan driven smoke unit, at least it's done it for all that I've converted.

 

Thanks John. Did you modify the smoke unit on your K-line Tank engine?

I have not tinkered with the smoke on the Tank Engine, I was happy with the output the way it works currently.  I adhere to the old saying: Don't fix what ain't broken.   I've done a number of other TMCC locomotives.  Basically, I drill out the intake hole and remove any sleeve and repack the smoke wick.  The other mod I do if I'm still not happy is use a 22 ohm resistor to replace the 27 ohm stock one for a bit of extra heat.

Hi John, A bit off topic but related to the K-line Tank. What speed steps do you recommend for Cab-1? And what if I upgrade to Legacy when they become available again? I do not really understand the choices so I run default 32. I also recall reading about issues with the smoke unit if one changes the chuff rate. I do not understand that either and run default chuff. Seems to work fine but I am not sure if I am missing added functionality in the default settings Thanks Fred

My tank engine has had the K-Line cruise module replaced with an ERR Cruise Commander, so I don't have the same chuff generation as you would have with the stock K-Line cruise module.  If you use the K-Line 128 step mode, you can set your CAB2 to R100 mode and have good control with the throttle graph and the keypad icons active.  I run all my ERR stuff in 100 step mode and use R100 as the control type on the CAB2.

 

For the CAB1, I'd also probably use 128 steps for the K-Line cruise, you get plenty of step resolution.

 

My chuff rate is determined by a magnet and a reed switch on one of the pilot wheels.  I added a second magnet and get 4 chuff/rev, that works for me.

 

Thanks. I will give it a try on 128 steps. Fred
