4-4-2 smoke unit question

I've done that.

It does work.  It's a lot easier on the reverse unit w/o all of that current going through it, and the smoke is better.  The modification was to keep the operator from overheating the smoke unit in neutral.

When you wire the newer style directly to the track, you will have to eliminate the LED used for the headlight. (Some of the later versions have a LED included)

Thanks Chuck,  That is what I did on my 1993 8632 NYC Central. 

Thanks Rob,  I left the on/off switch in, but I am glad I went through the trouble to convert it, this 2003 Pensy Flyer is better looking, has two men in the cab.  Now if I can get better output on my Polar Express.....

If you want to get clever, I had an MTH that I converted to TMCC using the ERR Mini Commander.  One of the problems with the Mini Commander is I had no extra output to control smoke, so whenever the track voltage was on, the engine would be pouring out smoke!

I built a small circuit that senses the motor voltage and closes a relay to switch on the smoke only when the locomotive is moving.

Very informative.  I just bought a TMCC Berk from late 90's that is a terrible smoker.  It's new and suspect it's wired the same.  Would that be so, & rewire would help?  I can picture why they wouldn't want it sitting there at full voltage.

Sorry for butting in but it is so close to what I have been wondering.  Thanks, John

I have a PWC Berkshire with TMCC.  I just bought it, new, never run.  I'm used to Legacy but have recently been playing with an old 726 from my childhood.  It spawned the interest in another Berk.  One I could use TMCC.  It would be fun watching it blow some smoke up in the air.  This thread helps me think there may be an option.  Thanks
