I have a light brown plastic fake lumber stack that has a circuit board inside and has a on off switch on the bottom and another switch that has 3-4 on it. There is a jack on the one end. Was wondering if anyone knows what this Lionel product is. There are no model numbers on it. It is about 3.5 inches by 6 inches long and 1.5 inches tall. Thanks

Looking to buy a 2020 Lionel VisionLine  SP Daylight GS4

Please let me know if you have one to sell or know where I can buy one.

Thanks!

Forgot to mention Using a MRC pure Dual power a/c transformer as the fixed power source if that matters...

CW-80 would work indeed. It has a separate programmable 0-18 volt output for accessories. Later on you can always add another Transformer to the layout as you expand or go bigger like a ZW and make the CW-80 the secondary.  All kinds of possibilities.  Be sure to get an instruction/setup  manual for whatever you buy.

Hi Greg
Glad your son has taken up the hobby. It's how my dad started me off with my first set in 1958.
 By "Controller" I assume you mean Transformer? For right now the cheapest and easiest way is, If he is going to stay with the hobby, then pick up another transformer that has  multiple output(s). Lionel makes many.
What usually is done is, as the layout becomes larger or permanent, you either upgrade to a multiple source transformer like the ZW (Which has 4 outputs) or one of the others that has multiple outputs.  Most folks will put their accessories on a separate source, Another output is used for constant voltage Power for  your switches and yet another 1 or 2 outputs for train control depending on how many isolated track systems you have.  I have more than one transformer running and I won't get into that right now. It takes a little bit to correctly set that up. Lionel has videos on all of this you can watch.
