Reversing Trolley with Time Delay

You can purchase one from Dallee Electronics that will do exactly what you want. I don't know how the price compares with building one yourself, but I've used one of theirs for many years now without any problems. Just a thought.

I would like to have the same for a couple of trolley lines on my layout. The only one I found on the Internet is here:

"The time that the SHUTTLE waits at each end of the track can be individually adjusted from 30 second to more than 5 minutes. The circuit can also be adjusted to control the acceleration, braking rates and maximum speed of the SHUTTLE."

I tried to price the components (from Radio Shack) for the first circuit, and got a price close to what the second one is sold for complete.

Does anyone have any experience with these circuits, or buying them from R. Paisley?

Try some other online sources like mouser.com or digikey.com Those parts should be under $10.

Rob's circuits work quite well. It's hard to go wrong with him.

I also carry a unit already assembled for $29.95 plus shipping.

Thanks for the quick feedback.

I've built a circuit similiar to the 'cheap' version for the smallest layout I ever built. It was on a 1x4 board 30" long. N-scale. Bachmann Trolley. I didn't bother with the diodes to slow the thing down. Built it on perf-board from Radio Shack. Worked fine for it's intended use (display).

What I'd like to do is have the trolley run from point A to point B, pause for 15-20 seconds, and then automatically return back to point A, pause again, and then start over.

Opps! Forgot to include the url:

Kenny, I do the same type of setup at Christmas. I run a On3 Trolley car on a point to point line using an Aristocraft reversing unit. Aristocraft is a "G" scale manufacturer, but the reversing unit they sell works with any scale. Basicly, you need to put a "gap" in one rail at each end of the track, and solder a "diode" across the gap. The unit itself is just a timer circuit which changes polarity at a preset time. ( this is variable depending on the length of your track ) The trolley will run to the end of the line and stop at the gap until the timer changes the polarity. It will then reverse & repeat the process at the other end. Very simple to setup, and cost around $50 on sale.

I have some components from Pocono Mountain Electronics which I had intended to use with an On30 trolley. If you are interested in them I'll sell them for 50% of what I paid. Included is the reversing unit along with a special track section that allows a switch to be connected and controls the polarity.

E-mail if interested and I'll provide more information.
