Vision line Big Boy with smoke issues and questions about the Force coupler effect

without the legacy vision line remote you can't control the special effects! I have the Niagara Vision line that was the first one with force coupler effect, as the engine pulls the car on a hill; then the more cars will increase chuffing sounds! it's a pretty cool feature, I thought only the Niagara had the force couple effect! the Niagara also had popoff effect which automatically pops off while the engine is at idle!

also sounds like you're putting in too much fluid!

You should be able to hear the difference with the force coupler,  with engine moving slowly hold the tender back with your hand.  The chuff should deepen.  Fyi the force coupler is not actually the coupler, rather its on the draw bar of the locomotive.  I think they should call it something else, because has nothing to do with the actual coupler.

I noticed my main stack was a little weak when it came to smoke. Anxiously I added more smoke fly and it’s much better. Always worried about adding too much fluid

Have you seen the size of a dual Lionel smoke unit?? If you actually saw the massive size- even compared to the typical bottle of smoke- your concept of overfilling it should be free from your mind.

The smaller smoke units, stay within limits, but the big units on most every large legacy steam especially when main and whistle steam or other effect is the dual unit- 20 drops is not even beginning to add fluid.

Thx Vern good to know

I cite this https://ogrforum.com/...-legacy-tmcc-engines

and also see the size https://www.lionelsupport.com/...02-DUAL-SMOKE-LEGACY

Keep in mind the size of the motor and impeller and there are 2 of them side by side.

SMOKE UNIT IMPELLER / .430" DIAM

So let's estimate the unit is 1 inch square in the cup area. If it was 1 inch cube, that is 16.387064mL, however the depth is say 1/4 inch we can use and fill. 1/4 of the volume is 4ml.

I've seen estimates that say 20 drops is 1mL. I'm just trying to show rough math and estimations, why 40 drops is not an unreasonable amount given the size and capacity of a known dual unit. Even if the wick takes up some volume, again, 2mL of fluid in a guestimate, should not result in an overfill, even if the smoke unit had some in it before filling.

Yes, 100%, on an individual aux smoke unit, the chamber is smaller and so yes, a smaller and more careful fluid fill.

Typical OGSU unit used for some individual smoke features do to mounting location and distances not practical for dual unit.

Wow that’s impressive, thx again Vern

Hi Tom, i’ve tried running it real slow and don’t hear much of a difference. But next time I run trains, I’ll try holding a tender back a little with my hand and see if that makes a difference. I did realize that the effect is on the drawbar and not the coupler. I made sure of that before I ordered it because I put Kadees  on everything. Thanks for your help. Joe

I have the vision line Niagara ill try to capture it for you on video.

I tried holding my tender while big boy going slowly and didn’t really hear a difference. Hopefully that doesn’t mean it’s not working.

Do you have the function enabled? It is a function that has an ON/OFF programming option in the previous Legacy version of this engine.

page 18 of the manual https://www.lionelsupport.com/...%20Big%20Boy_web.pdf

Oh i thought it came with it on, I’ll check and also check engine manual. Thx

Here is my post about some of the things you mentioned.
