I am lighting a 1910 style observation car. For the main interior lights, I am using the Minitronics modlel # 100-ICL-01 HO Scale Interior car lighting. The capasitor makes the LEDs have consistent light with no flickering. So far so good. But now add a drum light, side marker lights, and a porch light on the rear deck - all LEDs, all with their own resistors pre-wired in, but no capacitor

Does anyone know where I can find what capacitor I need (I don't even know capacitor nomenclature), where to find/buy it and how to wire it?

Hi gang. I'm looking for simple and economical occupancy detection circuit to follow a train from staging through a helix. I'm thinking an infrared detection circuit to turn on a series of LED's as the trains pass to and from staging and through a long multiple loop helix would be the way to go. This is for a friend that has a limited budget. I'm willing to build them for him. I just don't have a circuit diagram. 

Any ideas or product recommendations? 

Hi everyone,

I am looking to add a headlight to my brass 0-8-0 made in the 1960's by Tenshodo. Does anybody have good tutorials on how to do this or recommendations for lights/leds to use? The light is not mounted to the smokebox and hangs out from it's center on it's front face, see the Great Northern C-1 class 0-8-0's for a better picture.

I am doing a two phase DCC conversion starting with the headlamp and motor and then installing a light on the tender with a speaker later.

Thanks ahead of time.

Hi all,

My train club recently asked me to build a locomotive for them, to run back and forth on a mining line above the club's O/On30 layout.  The donor is one of the HO scale Bachmann Christmas Trolleys (http://shop.bachmanntrains.com/images/HO_Scale/61040.jpg).
