The main 33m oval is in one piece. All welded joins except the removable points which have welded plates at the bottom of the rail, double bolted together. No expansion joints as 2/3 of the track can move on the road bed - enough, I hope. I calculate about 1cm movement from 0 to 40C...Still have some levelling and ballasting to do but...
And still have the Y to do, but have everything lined up and the track is nearly levelled - which affects the levels on the Y of course.
