As Chip said, commercial crossings come insulated so it's pretty straightforward. Joe, I don't know exactly how you are planning on running the separate tracks with the crossing or how old your sons are. The one issue you may need to consider is what "potential disaster" could happen at the crossing. Will each separate track cross at a 90 degree angle to the other, thereby inviting a "corn field meet"? Something to think about...

here's a link to the Atlas crossings.

Here's a link to some track plans in case you get stuck for ideas. I don't know how old your sons are, but you might be setting yourself up for some wrecks at crossings. You could also consider a double loop where they could each run a train on 1 loop at the same time. Remember, some tracks are different "code" (or rail height) (code 100, code 83 ect.) Remember to buy all the same code track. They can be mixed on more advanced layouts, but that's another story.

I think that using Atlas components you can do this without too much difficulty. You will have two cabs (power packs), use Atlas Selectors to choose which cab will run each section of track (block). Have a relatively short piece of track each side of the diamond so that the diamond is a block of its own. When they are approaching they will have to move the switch to their controller and BE SURE that the other train isn't going to t-bone them while they are on the diamond. They should be able to have interchange tracks so they can exchange cars with each other too! Might want to get Atlas book on wiring to better understand some of your options.
Glad to hear that the boys are interested, hope they stay that way.
Have fun,
A crossing has the two tracks isolated from each other.
You can build a larger DC or DCC track and give each child control of a train on the larger track. Much more versatile if one child loses interest or just wants to run alone.

I am just starting out on designing a layout for my two sons and want them to each have their own DC track to control. I have not been able to find any info on how to create a crossing point (a diamond?) where the two tracks meet. Is that possible with two separate DC tracks? Thanks...
