I am always having trouble seeing if whistle smoke actually working with smoke stacks so close so I made a fix!

 

I had some evergreen 1/8" tubing laying around so using my modelers saw and miter tool I made a 90 degree elbow.

 

I filed just enough off one end so it would fit nicely into existing whistle assembly and just high enough to clear the red valve handle as well.

 

the results now I not only can see the whistle smoke it goes back towards the engines cab no more integrating with main smoke stacks.

 

I painted the white styrene with engine black paint blends in rather well. I did not glue in place it merely is a friction fit assembly.

Yes you did.
 
The stacks, whistle, and blow down smoke units can be shut off using the switches under the sand dome hatch.  You can shut of each individually while maintaining the others.  If you use CAB2, that will shut off all units as a group.

my understanding is if you turn smoke stacks off you also lose the whistle smoke.

 

did I miss something?

 

 

 

I think there are several things in the manual that were cut and pasted from other manuals, and not proof read.  The above example as John points out is just one of several I found.  Regarding the smoke, I think part of it is also that the whistle suffers from the same problem as the blow down, that of the smoke exit port being smaller then the tube leading to it, thus the smoke shoots out at a high speed which means you don't see it at the whistle.  Think of sticking your finger on the end of the hose to make the water come out with more force.  I also have noticed that if I turn the stacks off (Via the switch under the dome.) that the whistle and blow down smokes get thicker, which makes them easier to see.  So all the resisters' power may be coming from the same source internal to the locomotive and with the stacks off more power is there for the other 2 and they can heat better which gives better smoke.

With only the main smoke switch off, there was a little puff of smoke from

the whistle smoke unit each time the whistle was operated. The track was then connected

to a Z 4000 transformer at max voltage. There was a large volume of smoke from

the whistle when operating the whistle.

The whistle smoke unit will operate by itself but it seems to require a high voltage on

the track.

 

 

 

 

Only issue with whistle smoke is at startup seems like it takes 5 minutes to really produce smoke!
I have tried only 3 drops no help, tried 10 additional drops blow down the fill hole no help.
Tried the 1 line pipette still no joy I have litterally timed it 5 minutes to smoke whistle actually producing smoke since brand new.
so do I just have a whistle that's like a human with a slow to awake liver and just wait it out or is there something else going on here??

One thing to check is the "loaded" track voltage. Set up a DVM meter near your BB and measure the voltage at: idle, stack smoke, whistle smoke, blow down smoke and forward movement and then ALL of the above...The BB is just that, a BB. It needs a lot of current and high voltage to operate properly.

 

If you see the voltage drop a lot (not easy to predict "a lot" due to many variables) then you need lower impedance in your track. Improve wire connections to the track.

The operation of the smoke units vary with track voltage. At the voltage I was

using, turning off the main smoke unit off caused the whistle not to smoke.

Increasing the track voltage caused the whistle unit to smoke very well

even with the main smoke unit off.

 

When the BB manual was written and tested, the track voltage may have been

at a level that turning the main smoke unit off caused the whistle unit to

stop smoking.

 

Is it also possible that the internal power wires that go from the drive wheels/pick up rollers to power the internals (PCBs, smoke units, lights, motor...etc) of the VL BB are a bit under rated for the current needed at full load? If so, some operational problems may occur and a higher track voltage can help some what. I did notice on my VL BB that the smoke effects were much better at 18 VAC than at 15VAC using Z4000 and Legacy remote. I had only a 12 foot RealTrax straights with two power points.

Just guessing!

yes 18 volts is the magic number.  also I have noticed on mine maybe not yours if smoke set to low smoke volume for whistle smoke is same so set my smoke to high poof and away it went nice and thick.

 

I should email lionel and ask why for mine does that! and I did email them will wait to see if a cure available.

I also have blockage issues after filling be it 3 drops or 1 line of pipette for the whistle smoke only. almost acts like a homes water drain pipe not having a air vent line.

Yes, 18 VAC seems to be the sweet spot for the VL BB. The problem is, if you set the track at 18VAC "Unloaded", as you run the loco,  lights and cars and as the BB goes further from the power feed source the actual "loaded" voltage will drop a few volts and hence the smoking effects will suffer. Now one can correct this by increasing the voltage back up to 18 volts while everything is running. But now the "unloaded" voltage can go up to , lets say, 20VAC if you remove cars and lighting and so on, so if you power up the track next time with only the BB at a stand still and at the last higher voltage setting, the Legacy circuits will see 20VAC!!! According to the Lionel VL BB manual, over 18 VAC can damage the boards. So it can be a "catch 22"

 

I am new to the Legacy/Lionel locos so I am still learning and I find myself setting the voltage at 17 VAC to start with, as I run the VL BB, I measure the voltage with a DVM right near the loco and I adjust the Z4000 accordingly. Then the BB sees 18 VAC almost all the time. The nice thing about the Z4000 is that one has to move the handles to zero on start up so there is no danger of over-voltage to the BB next time you power it up.....

At reduced voltage, the whistle smoke unit may not get hot enough to

smoke very well. With the main smoke unit turned on, enough heat from

the main smoke unit, added to the heat from the whistle smoke unit, may

make the whistle smoke unit output very good. Turning off the main smoke

unit will reduce the heating of the whistle smoke unit and make it look like

the whistle smoke unit is also off.

 Lionel smoke units work best with a "chopped sine wave transformer".Maybe part of the issue is the "smooth sine wave" of the Z4000:

 

 

Having said that, as John mentioned, if your losing a couple of volts at the track you may need larger/ more buss/ feed wires. Lionel also recommends a minimum of 14 ga in a command environment.
