The time it takes to learn the software.  A short learning curve would indicate that the program was easy to learn.  A long learning curve indicates that the program was difficult to learn, or has several options and features that require more time for you to master.

I have 2 connies and 1 light mountain that were converted to DCC.  I love them and have never had any problems...

If I am in a bind, I triplex them to remove tree stumps

I did this one... got AC and DC wiring backwards....

AC for accessories
DC for track..

Xtrkcad has now gone open source (Free).  Here is the link to the latest version of the software. I believe it is version 4.01

Great stuff - very powerful, but has a steeper learning curve compared to Atlas.  If you are going to use any track other than Atlas - then this is the way to go.

Barry,

thanks for the tip - We do not have any trolleys right now - but I will look for one of these.  This would solve a bunch of problems.

thanks
Jim

Thanks all - got it - much appreciated.

Shameless bump --

thanks for the information.

You answered a lot of questions.

It sounds like the bumper is just a shorting device, and the when the trolley closes the gap, a short triggers the circuitry.

Any other gotchas in need to worry about?

thanks
Jim

I have a couple of questions about the reversing trolley set - can't seem to find the information I am looking for.

It appears that the time delay and reversing is built into the trolley itself and is not a function of the power pack or bumpers.  We think that when the trolley "hits" a bumper - the direction change is a mechanical vs. electronic change. Is this true.

If the above is true, can additional bumpers be purchased.

Also, can standard flex track be used?  We have a couple of tight spots that require 8" radius.

Also the power pack powers the trolley like a standard power pack - nothing fancy. We plan on using it, just want to make sure there is nothing special here.
