Chad, If you're really into fiber optics then I guess your plan is pretty good. I'm not sure how expensive fibers are when compared to wire. Also, you don't get quite the same effect with fiber optics because they are somewhat directional I believe. Two observations: you can increase the life of bulbs by adding a dropping resistor or wiring two bulbs in series. This also dims the output which actually helps things appear scale, although unless you dim the room lighting you may have trouble noticing the lights at all. Second, you should have an independent power source for lighting whenever you consider using the numbers of lights you are implying in your post. I believe most accessory lighting is connected to the AC (accessory) terminals on your power supply which also drives the switch machines on most layouts. It would seem easy to overload a power pack under these conditions. BTW. I recommend using a Capacitor Discharge unit whenever you have more than a few twin coil switch machines. Just my two cents. Good Luck - Ed
