I’ve finished setting up the train under the tree but I have a problem. I’m running an old American Flyer HO with a modern(ish) powerpack. I forget the name right now but they still make them. The powerpack is about 10 years old but has only been used for about 1-2 years. I have to run the pack at about 85% to get smooth motion out of the train and after about 30-45 minutes the train slowly runs slower until it dies (light even goes out). I felt the train and it was fine but the powerpack was pretty warm to the touch.
I’m thinking that it’s getting too warm and there is some sort of safety that is shutting it off. My solution (plan) is to drill some holes in the cover (with it apart of course) or cutting a hole in the back and putting in a computer fan to suck out the warm air. I’m going to hook up the fan to the accessories power.
What do ya think? Or am I wasting my time? The pack runs fine with my 2 protos.
Are you sure that your trains aren’t so desperately in need of cleaning and lubrication that they are overloading the power supply? It sounds like you are considering treating the symptom here. I’d be concerned about drilling holes in the power pack’s case for cooling purposes. Any UL certification would go straight out the window at that point and you’d be liable for any accidental shock or fire event caused by spilled liquid or a errant pine needle falling inside the case and combusting.
I have the train running as smooth as possible and it is freshly lubed but like I said it does take about 85% to get it to run at a 50% pace smoothly. Maybe I need to try and run it w/o the cars to see if that’ll help.
Sounds like your transformer/controller may be undersized.
Disconnect any AC accessories – if that doesn’t help run out to a hobby shop, seek advice and/or buy a more powerful one.
Once modified the insurance company may decide that your claim is null and void.
Micheal has the right idea about going to the local hobby store I would also check the track and feel for any warm spots. This may indicate a possible short or ground.
You may just find that the power power pack is faulty. Check the trains motor for heat and smell as well.
An alternative is to build your own if you have an extra PC power supply lying around. You would only need a power transistor, heat sink, dpdt toggle, potentiometer, some screw connections and a case.
