Small update, without photo's as my camera has gone awol.

Some more track has been laid, bought 2 boxes of track screws.
Made a wooden circle, basically a left over plank, screw on one side to centre and then drilled holes at different track radiuses to mark off the cut lines on the plywood. Works great and one sheet of plywood has been cut this week.
Have 5 more track segments that are prepared.

More on their way.
Also spent some time looking for my bridge parts and glad to say that I found all of them.
Lots of ideas running around in my head, even for the scenery already.

If daily work would just not interrupt me all the time.

Cheers.
