Lionel # 610-PCB1-045 Smoke Board Question

It helps to use the correct part number, it's 691-PCB1-045.

Yes, it has the 5V power supply for the fan.

I agree with you 110% John! After dealing with A/C engine parts for 40+ years, I always take the P/N off the article in question - shown in the attached photo. The sad part is the Bill of Lading with this latest parts order DID have the correct P/N-I just didn't cross-check it-dumb me!

Again, thanks for confirming it does regulate the fan motor voltage on this board.

I never noticed that part number on the PCB, but a search on Lionel turns up nothing for it.  Can't fault you for that number!

John: The more I really look at this PCB, the more odd stuff I see; " Lionel Trains' and "USA" are mis-spelled. I notice it says "3rd Rail' along one edge. I wonder if this is a Chinese "knock-off" of the regular Lionel part?

I purchased it in a n order last week during the 50% off sale @ LIONEL HQ. BTW, the smoke resistor did come with the fiberglass sheath over-since removed.

It's made in the UOA as well, don't know where that is.  Odd thing is, I just took apart a smoke unit in my parts box, and it has the same PCB with the same silkscreen!  I think that was just a total screwup of the silkscreen by the Chinese maker.

As supplied from Lionel, that board will not work well.  It has the older style ceramic resistor installed which is known to not give off much smoke.  Do yourself a favor and order a new 27 ohm resistor 600-8141-055.  Install that in place of that ceramic resistor.  You will get awesome results.  I got this tidbit from Mike Reagan.  I upgraded every loc that had that board with the new resistor.  Best money spent.

For steam, I typically use a 20 ohm resistor and upgraded wick in the smoke unit.  For diesels, I use the 27 ohm resistors.  I think my upgrades yield enough smoke.
