forget the springs, go with the electricity

I think they may have changed model numbers, or it was a typo. The BPAP was recommended by their app engineer. This is the same:

They even have a BCAP3000, and a 15 volt module (58 farads):

and a 48.6 volt 165 Farad monster:

I found it was too big a project and I had other things to do, so all I have is a collection of parts and a crude prototype for testing steel V-groove wheels on a track made of pipe. I decided to try using a single rail because it would be much easier to lay, and pipe (EMT conduit) would be very easy to bend, and very cheap. I added "outrigger" rubber wheels to keep the contraption from falling over. It basically "worked" but the V-groove wheels slipped a lot. Now I am trying to do more with an AC motor controller so I can use 3 phase motors with better speed/torque control. I might make an electric lawn tractor. I can get just about all the wood I have cut in a few loads in my pickup truck.

There is an electric wheelbarrow that might do the job as well, although it might be awkward to control, and the rail train would still be way cool. Live steam, powered by wood, would be the most fun.

You should find a carny that's on its last legs/going out of business, and offer to take their little kiddie train ride off their hands for cheap. ;-)

(I'm sure you've seen them if you've ever been to a carny - about 12" or 15" gauge rails, holds a grownup on the engine and maybe a dozen kids - Hey, there are some here, as low as $13,875.00 =:-O

Have Fun! Rich

I know someone who has been involved in model train clubs, and he has had the honor of operating a live steam train at Leakin Park. It is about the gauge of the kiddy ride trains, or a bit smaller. I know someone else who is very big into Garden Scale railroads, which are not big enough to ride on, but are designed to be set up and run outdoors (with realistic issues of weather and maintenance to contend with). There are companies that manufacture rails and rolling stock for riding trains, probably about 1/4 scale. Also quite expensive. It's probably even cheaper to buy full size surplus rails, cars, and engines, but the cost of transport would be a killer (unless you are close to a rail line and can connect).
