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 second one sells for US$30 plus US$5 shipping. It has delays at both ends,
and acceleration and braking sections at each end. From the web page:

"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?

I'm interested in building a very small N-scale table top layout in time
for Christmas. Basically, it will just be winter scenery with a trolley.
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.

Although I've not used any of his products, I'd certainly consider Mike
Tennant's Iron Pengun Electronics reversing unit. It's inexpensive and
appears to be what you'd want to use.

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.

Circuitron has 2 units the ar-1 800-5400 is a simple reversing unit.
The AR-2 800-5401 has adjustable delay and can be setup with stops
between ends. the AR-2 lists for 54.
