Train Control

The UCW has been equipped with command control since 1979. Our system, of choice, for many years was Dynatrol, which is an excellent system and performs very well. We began to tax the limits of the 18 channels available from Dynatrol, with additional motive power and increased traffic volumes, so a search was conducted in 1992 for a new system offering more channels.

That lead me to Rail Lynx which is an infra red control system providing a direct link from a hand held transmitter to the locomotive (line of sight), meaning it's cordless providing total walk around freedom. It features 255 channels, MU capability, built in flashlight, front and rear headlight control, power matching capabilities, push button direction control and a knob for speed control all contained in the hand held unit. It is an excellent system and is all but transparent to the operation of the railroad.

Infra-red Sensor, Receiver and Headlight Installation

On the UCW IR sensors are installed in the Cab of each engine. I purchase large sheets of PC board which have traces on them from which I cut smaller boards that have 3 traces on them. I ACC the small boards to the engine frame which allows me to solder the senors to them so they stand upright with the bubble pointing toward the windows. Most of the receivers I use are mounted above the motor from which I hang the headlight LED's so the rest against the light bars in the engine. By installing the receivers, LED's and sensors in this manner keeps the wiring very clean and contained within the engine frame, allowing the shell to be removed without any wire interference.

Battery Power

One of the neat things with line of site control is you can run the engines on battery power. The prospects are limited do to battery size but who knows what the future holds. Below are a couple of pictures with a crude battery setup. I have different battery holders to try which I'll post later. With pure DC power control is excellent and the motor runs very quiet.
