Burning Switch tower installation?

Hi, I got the Lionel Burning Switch Tower for Christmas (one of my fav accessories), but it didn’t come with any instructions. Does anyone have any idea how to hook it up or where I should look to find such info? For ex, I dont know whether it operates via a weighted track section (ala the gateman) or if it needs a switch (mine came with neither). Thanks much, any info is appreciated.

This is a great accessory. Mine really puts out the smoke. Go to the Lionel Website and you can find the manual there. Its found under customer service. http://www.lionel.com/Products/Findex.cfm

Thanks Dan! Found it.
