Here's what I did (one of two, actually) during a couple of days in Hango...

You can see the tab system of fastening the track pieces together, and below, the self-acting switching mechanism that allows you to run through an open switch, and at the same time setting the switch - a weight, not yet installed, will faciltiate the switchover, and keep the point in the new position.

This is my planned, new layout.

With the two self-setting switches (top of sketch) you can run two laps around almost the whole the track without retracing the route in the same direction. Follow the line (disregard the broken line) from an arbitrary starting point, and memorize the "new" switch setting each time the switch is thrown by the train, and you'll see what I mean!

This was called a "moebius" track by one of the listees!

A couple of weeks later, some more welding work, and I have a bunch of curved tracks that will suffice for the loop. The X-ing is just a welding X-ercise, not to be used right now...

The is what the final track layout became... no track in front of the door - no risk for anyone stumbling, or getting run over by a train sneakingly coming along the wall or around the corner, as possible in the sketch above...

Laying the track on the lawn, I put strips of dark green tarp under the track pieces (it doesn't look dark green, but that's because it's covered in pine pollen - LOTS of that this year!) The plastic will prevent the grass from growing up between the rails, and will make it much easier for me to mow the lawn - something I have to do at least every other week. No other family member will even touch the mower... (I wonder why? ;-)
