Nick Jr Bil, thank you. I do get a good idea once in a while. I thought of cutting the blades off, but those little fans are centered on a pin point and even the slightest imballance would throw them off and wouldn't spin. LiG

choochoowilly That is neat, I use these from gfhappyboy on Ebay too control 5 volt smoke units and throw in a 100 ohm resistor for head lights and flickering fire box and they work great. I particularly like the way you slowed down the fans by just painting ever other fan blade, good looking engine

Nick Jr Installed an adjustable voltage limiter, access to adjustment is through the heat generater exhaust. Assembled a simple circuit so the drive fan gets 4.5V and the fans spin, the drive motors are still idle till the track voltage reaches almost 6. No matter the train speed the fan speed is constant.

Nick Jr Jerry, thank you. I darkened the other fans. I decided on track power and am now putting finishing touches on the circuit the drives the supply fan. LiG

Jerry Barnes That worked great.

Nick Jr Rob advised me to try and make the fans run as slow as possible so they can be seen. With limited control of the supply fan, and the roof fans having 8 blades they were a blur. A little trick on the eyes, I darkened every other blade, I will do the others next time. LiG.

Scott Nick - your mate would love the NB30 that is preserved and runs on the Pichi Richi Railway. It started life as a Vulcan 0-6-0 saddle tank loco and was converted to Diesel-Electric loco that's still being operated.

Nick Jr He also added that since diesels don't have the rod motion of a steamer feature movement gives the model life. LiG

Scott Mate, that is super functionality especially for a smaller scale.
