So I'm finally just about at the point of installing all the final fascia controls for turnout control, signal repeaters, etc.  I'm curious to see what others have done in terms of layout, labelling, switch types, LED colors, etc.  Any thoughts on things that have worked well for operators understanding the controls vs. things you'd change if you were re-doing it?

I currently have a mix of sound decoders in various locomotives (i.e. Loksound, Tsunami2 and Digitraxx).

I use JMRI for programming and updating CVs, etc.  I find this to be a challenge but I am learning.

Is there a more user friendly app to program sound decoders?

For example, I have an older Atlas MP15DC.  I'm replacing the old QSI sound decoder with either a Loksound, Tsunami2 or a TCS WOW decoder. . . not sure yet.

I think I know the answer to this question, but I just want to confirm my thoughts
 

I'm putting a long 'Y' turnout at this point on one of the two mainlines that are entering my external helix structure. The 'Y' turnout is allowing the train to 'recirculate' around the bottom of the room, rather than going up the helix. The trains might be entering this 'Y' either from the points end OR the frog end at particular times.

Upgrading an HO Athearn Genesis GP9 for a friend.  Installed a Tsunami-2 decoder and wanting to install “led” headlights. 

What I am looking for is pre-wired led bulbs that already have a connected resistor.  Probably around a 1.5MM given the size of the headlight housing on the Athearn. 

”Any recommendations?” 
 

Did see where Athearn has replacement led lights but the price seemed excessive and there was no information if a resistor was already built in.
