Hello all, just a heads up for all of you who want to signal your layout/modules with true to scale N scale signals... Showcase Miniatures has the fiber optic/LED holders now available! http://www.showcaseminiatures.net/century-foundry.html this a great item that really helps capture focus t all the light from an LED into the flared end of the fiber optic cable used to light the their beautiful signals. This system allows a modeller the advantage of being able to keep the LED seperate from the signal (if an LED burns out or shorts, the signal isn't kaput)...also, this allows for a beautiful scale signal head (the Showcase Miniatures' one is fantastic!) I'm really excited to see these beautiful products being made available to us. ~Bruce
