Hello Ed,-
I have a data sheet on 6152 and I "think" the measures are the same - 6152
is for Profi tracks as you probably know.
6152 measures are as follows
310 mm for the bridge and inner rim as you write
385 mm for the outer rim
If you mount 2 6153 tracks opposite each other the measure is 465 mm.
Fleischmann suggests that the hole for the turntable should be 340 mm and
the thickness of the plate should be 25 mm.
I hope this will help you.
I am willing to send you a jpg/pdf of the datasheet by e-mail if you want.
Best regards
