My name is Gary Toothe and I attended my 5th Model Railroad University in Springfield this January. I had a chance to experience the Fiber Optic lighting system made by Dwarvin Enterprises on an N-track module I assembled. The effect was magnificent! Being a Z-Scaler I believe the system will be essential to bringing interior and exterior lighting to my layout. I look forward to working with Dwarvin to take the Z-Scale Carolina Central to a whole new level.
