I have gutted a couple of fiber optic Xmas trees before they went in the trash to get the fiber optic filaments out.  They are fairly good quality and I plan to use them to light up bldg, water towers, cars and whatever on my next layout.

Some strings of Xmas led lights have very sharply focused lens on very bright leds.  I've popped a bunch of those to use to drive the optic filaments.  Maybe I should say operate the filaments since people get real upset when the "drive" word is used.  Wrapping the led-optic interface in Xmas tinsel or alum foil should get a decent transfer rate.

Sorry mellow, I don't have the data rates in a pdf file yet.

This doesn't answer your question exactly, but there was a cool thread about 4 months ago by a very talented guy that ran fiber optics through his dining car, and the end of the cable was used as candles on the tables.  Simply awesome.

At the moment I forget that very talented guy's name, but I heard him speak on a Zoom presentation, he is a retired college math professor and lives in Canada. Others on this Forum also saw that presentation and know his name.

I believe that the Canadian fellow in question is Jack Pearce (sometimes on this Forum named “Pierce”), who I have seen at York in the past. He did dining car interior detailing and lighting for 1/43 scale motor vehicles. The dining cars did use fiber optics for candles on the dining tables. The last time I saw his stand at York, admittedly some years back, he was effectively logjammed with dining car orders and was not promising delivery of new orders any time soon.

Unfortunately I don’t have the name or contact details of his business but it might be Darwin as referred to above.

Bill, to change color Dwarvin recommends painting the end of the fibers with translucent paint. I use an orange from Tamiya for a couple of buildings.

My electronic skills are meager so I use Dwarvin's integrated railroad crossing kit to accomplish blinking lights and bells.

I have three of these kits, one for each set of crossing signals.

There are five wires to connect into each screw terminal: two for the crossing signals, two for the sensors (in the foreground below) and one for the bell. The fiber, two for each crossing signal, is inserted in the body of the module. I use a Dwarvin wall wart for power to each DFL. (I can't remember the power requirements.) They also have a sensor that is installed between the rails.

I was on Dwarvin's website this morning and it says they were purchased by Trainz.com March 1.

Yes they are that is where I became interested in fiber optic. They say they plan expanding the line in o scale. Hope that is tru. Thanks for your information.
