Here is the breakdown of your caboose, however, the 6102722050 smoke unit is unavailable from Lionel.

Forum Sponsor S&W Parts does list the part as one they inventory.

It looks like you will also need some supporting parts as shown in the diagram.

Thanks for that link.  It is helpful.  Not seeing the smoke unit at S&W plus the mounting bracket seems unavailable.  The correct smokestack is available from Lionel though.

One just has to work through the various Lionel and Vendor Part Number formats:

And as a bonus, the next line down is the mounting bracket!

Installing smoke units in a caboose

I believe the smoke units are just not inventoried yet, I suspect they will have them on-line at some point.

This is the AA-1600000 HO smoke unit, currently listed as out of stock.

This is the AA-2100002 single resistor smoke unit, not much bigger and still in stock.

Thanks to both of you I now have some choices.  I should have looked harder.

John

Is this the correct operating voltage for this application if I try to duplicate the original setup?

For a conventional setup.  The resistor in the caboose diagram is a 1W 10 Ohm looks like a wirewound.  I can center mount it and use a hose to run up to the stack (which Lionel has) or a makeshift brass rod.

John

No, you will burn it up. You need the 12-14 version

John,

What would the wiring diagram look like for this as I'm thinking of upgrading items like a caboose and a building smoke stack?

Thanks!

OK Thanks.  With the same resistor?

John

Yes, use the same resistor.

For the HO smoke unit, you need a regulated 5-6 volts for the resistor and around 2-3V for the fan.  I typically selected a resistor for the fan from the 6V resistor supply to yield a suitable voltage for the fan.

Closest two are

#6   10-14v    140 ma

#7  11-16v   140 ma

I would guess #7 right?

John

I'd use #7 if you're running command.  If you're running conventional, then I'd probably go with #6.

Thanks John.  I'll order #6

John

Yes that is the correct choice.

Thanks Chuck.

Attached is a link to a website that sells Seuthe smoke generators.  I am not promoting the site per se but what they have is a very nice listing of the various Seuthe smoke generators currently available.  Great for reference purposes.

Hope it proves useful.

Thanks Kazar
