This has been simmering in my head all day: instead of relying on track power for Gn15, why not make it battery powered? At 4:55 mountain time I hooked up my little HO scale hustler to a single AA battery and so far (about 1/2 hour) it has been running fine.

The way I see it, remote control doesn't make any sense because the layouts that Gn15 operate on are usually small, so I was thinking, why not just use a battery, hide it in the locomotive somewhere, and have a switch disguised as a lever to make the train go forward and backward:!:

The locomotive will run at low speed, and won't stall due to dirty track. and finally, my favorite, the locomotive could be run on reverse loops without any wiring. To make the battery fit, I've put it in place of the weight, so the locomotive can pull just as many cars.

Tomorrow I'm going to get thereversing switch, and I hope to give a progress report.

But I have to ask, has anyone else tried this before? Would anyone like to try?

I suggest you check out our Radio Controll sub-forum, on Freerails

All things you mention have been discussed at length, I am sure you will find it interesting and informative.

Be happy

Battery power is the only way to go with scales larger than HO. You can fit a Losi ESC and LiPo battery in it and have RC in the event you run it on a larger layout.

James-battery power in large scale is not something new, our English friends have been using batteries and DPDT switches for years on their micros and even garden lines. No, I don't suggest using r/c on a micro...that's like using a cannon to shoot rabbits. However, Dwayne is right, you might want to run the loco(s) on a larger layout sometime and you may wish you had the ability to operate the loco. But do your own thing, don't let us tell you what to do.

I haven't done it yet but that's exactly what I'm planning for a couple of short Gn15 mine trams on my outdoor layout.

Well, that depends on the way you want to operate your layout.

My Gn15 Layout that I'm currently working on, is designed for point to point and shunting operation. I need direction and proportional speed control.

But as Don already said, have a Look to the RC section.

My RC-equipped locos you find here

:doh:Well, some news that I must share which brings a setback for this project. Tonight I wired up the motor, switches, and batteries and something is not right. I may have gotten a defective DPDT switch because: A, it only allows the motor to run one direction, not both like it is supposed to. And B, the batteries (AAA) sized are heating up excessively, even when the motor is turned off. :doh:

possible explanations include:

bad switch (switch causing extra resistance, forcing the heat of the battery to increase)

bad set of batteries (sometimes happens)

motor is giving too much demand for the batteries (they are AAA's afterall).

I'll have to look into this tomorrow.:dt:

Could it be that:
The DPDT switch is not wired right?
That is another possibility that needs to be considered.
Center posts to battery + & -, one end posts to motor + & -, and other end posts wired diagonally to the motor posts. Then it should work. Is that how it is?

James,

from your description I would subscribe to Woodies suspicion. Perhaps it is senseful to post a sketch of your wiring.

okay, here is the diagram. I do believe it is wired correctly, and it is just that something isn't matching (amperage, voltage, or some other thing)



very proffesional, I know.;)

No-the motor wires go to the CENTER posts, the battery wires go to the END posts (either end). Try that out.

Normally, that would be something to consider, but I've wired these before. I have everything how it should be. on the diagram, the posts going to the motor are in the middle.

But I thank you because that is something someone else following this forum might get screwed up.

One thing that occurred to me is that there may be too much demand from the motor, so the batteries are over-heating due to that.

ohwell, back to square one:doh:

Well, I'll be dipped... Guess I'll go back to my antique power system and leave this high techie stuff to ya'll. But, what I said is still the way to do it.

Sieze ya later

You are right, the way you explained it is the way it goes. It's just not the problem in this case.

like I said, "oh well, back to square one."
