Off work today, a rare midweek day off. Been working too much over the last few weeks so needed a break.
Set up some tables outside before it got too hot in the sun.

Track is down on Module C.

The track is far from perfect but it will work OK. My curve and the cork it is on are a bit misaligned. I will trim the cork later. Still to be done is the wiring, both reversing and main power connector.

I mentioned that I ran out of (misplaced) insulated rail joiners. I made my own from Peco N-Scale insulated rail joiners and a Unijoiner with the metal rail joiner removed. If it looks like the two tracks are not parallel, you are right. Some when in the gluing process the front track moved a bit out of kilter. They are spaced correctly where it matters at the edge of the module. On the inside track, the black joiner is a proper Insulated Unijoiner. Beside it you can hardly see the Peco Insulated joiner.

Here is a group module shot from the inside of the loop.

Assembly was as easy as I had hoped. If it looks like there is a sag between module B and C, it is because the table has a sag. I've been using these folding tables since 2011 and they are starting to age.
The module set is large; 7' long by 4 feet wide. A bit of a deviation from our standard module size but this is what is necessary if you want a reasonable radius on the return loop.

The track join from Module C to B is not too bad.

On the left on Module C the curve ends at a BG4, then it connects to a BG2 with insulated rail joiners. Two BG1 span the gap and connect to a BG2 on Module B.
You can see how small the filler piece will be. I tried to eliminate it but it would have required a joint on a curve and that is something I did not want. I might be able to eliminate it if I inset module C into Module B. Something to doodle.

Lastly here is a picture of the loop from the end.

Look at all that empty space inside the loop. It cries out for something to fill it.

You can easily put a yard or an industry or two in there. Can't wait to see what you do!

Turntable and roundhouse get my vote.

Take care with turntable and roundhouse. Those facilities always belong to yards and they have never a direct track connection to the mainline. That means in this case that there must be an extra track from the yard nearby leading to turntable.

Of course. Yet, no one is bothered by our main line making a big U turn to send trains back in the opposite direction. It was just a joke, because none of us will buy a turntable.

But why not? An excellent turntable is available from Roco...

Having time to doodle on the computer, I redesigned the end loop.

This is a foot shorter and has no add-on pieces. I'll build the second loop to this plan. It should be easier to setup. Join B to C, then both to A.
Accumulating track pieces now.

Moving to larger modules makes some things easier.
My original long passenger station six module set used a lot of bedding track and had a many track joints to keep lined up.

Here is a redesign to two four foot modules with an optional extension module.

There are fewer and simpler track joints. It will be much more practical to build.

Feeling a bit gray today. Inventory ran to midnight yesterday. Finished OK but tiring.

Glued the power connector block and dual Frog Juicer to module C.
Wiring tomorrow.

Re frog juicers - I get the point about them automatically changing the frog polarity to avoid a short circuit. Do you still have to switch the turnout direction yourself, or is there a way you can get them to do this too, i.e. operate a switch machine when they do the polarity change?
