my critter runs on 2 AA batteries and has a dpdt switch. Total cost is about $5. As far as I know, I have the lowest cost motive power system of any garden train in the world. This is 32mm track at 7/8n18 scale.

Hi Alex...if you can do some soldering and you can aford about $50 the following link of my endevours in battery power for my garden railway may be of interest.

I use Li-Ion and Li-Poly batteries in all my large scale stuff now. I find the low weight, 3.7 volts per cell and super linear power output over the discharge cycle to be worth the extra money. These batteries do require a special charger however, and I only use packs prebuilt with over/under charge IC protection circuits which are slightly more expensive.
For control I use CVP's Airwire system. I find the DCC output and ease of split battery configuration to be very useful. And while the motor drive on the receiver board isn't the best (fairly low PWM and no BEMF), I typically use the DCC output on the board to drive a Tsunami or ESU Loksound decoder to run the motor(s) and provide sound for the model. This works in all but the most power hungry steamers. In fact virtually my enitre fleet of Accucraft breass steamers are powered in this manner with great results. For anyone interested in using this setup, just be sure to check the current draw of the locomotive carefully before installing anything.
I like everything inside the engine. That way I can use whatever consist I choose without being limited to whatever trail car there is with the batteries.
My battery of choice has been the 24 volt drill packs. You can remove the cells from the unneeded case and they slip nicely in thte average diesel and most larger steam models. They can be recharged by connecting the connector to the tracks (powered) and run trtack power while recharging the batts. has worked for the last year or so with no problems.
So, there you have my take on the subject.
