These are the Pennsylvania Railroad position-light signals I created with the Power Functions lights in my layout. I used 2 PF lights (not just single unless for the red lights). This creation is better than the last experimental version. I maybe consider the size of the signals targeted to "scale 8-wide". This creation was originally in the "Trains (LDD Edition)" folder, but later moved to the "Trains" folder. Please rate and comment.
About this creation
One day later, I recreated this signal (no longer a prototype), and it's just perfect.
An original prototype created on Lego Digital Designer made before the recent verison.
The Pennsy signals look realistic, isn't it? Also, why the background is all white instead of the usual one?
