The frog juicers only switch the polarity. If you want the train to control the switch, you need a separate system. Doing it with DCC and a stationary decoder is easy-ish.

One of the problems with the new loops is that they will no longer balance nicely on a table. They need two tables to hold them properly.

I have submitted a request to the show for two more tables. If they can't supply them at this late date then we will have to scrounge some on our own.

One solution I thought of is to skew the loops 15 degrees on the tables.

This requires two fifteen degree curve modules. Would not be too hard to build.

Track for the second set of loop modules is currently in customs in Ontario. Should be here next week at the latest

Hmmm, having modules hanging off the sides of a table feels rather precarious. I hope you're able to procure more tables.

Free tables are no longer available but we can rent two tables for $ 20.00 each.

Would it make any sense to buy a couple of decorator's pasting tables or suchlike? Then at least you'd have them for future use.

We are already bringing three six-foot tables and one four-foot table.

Extra tables were the trade-off known before the bigger loops were built. Myself, I don't like seeing more reverse curves in the second option, and the extra pieces are not in keeping with the goal of easier set-up. The extra tables give extra room for display and for working on the trains. So even renting the tables is okay in my opinion.

I bought the foam for the second new turn back loop last night.
A much better experience.
There was a young man working in the cutting area (didn't think to get his name) who cut my foam into four foot pieces.
No fuss, no muss, a quick job done well..
Picked up wire for the modules earlier in the day so now just need time in a not too hot location.

The first loop will be ready to test this weekend.
I am waiting for track for the second loop. It is supposed to arrive late next week.
For now I will glue up the foam and lay out all the track lines, ready for gluing.

Home by 7pm. Weather was Nice so I set up a table outside and wired the first return loop.
Started by cutting the module to its final shape.

The power connector cable was a bit long and messy so I went online and learned how to four braid.

The wires are recessed in groves on the bottom side. The pieces of tape are holding the wires while glue dries.
I still need to add 1/2" feet to bring the modules closer to proper track height.

Now to ballast and scenic the modules.

Was nice outside today so ballasted track on the first new return loop.

Still far from perfect but OK or now.
Finished before it got too warm. Left them outside in the sun to dry.

Later this evening when it cools down I will start the grass.

Then to start laying out track lines on the second loop.
