I think, 2860 and 2862 will be the right real part numbers for the solid parts for the new plastic train tracks, since this number is moulded in the real parts.

The Train Track 9V Point Tongue Right for sure has a different design, very close to the existing version of 2860.dat on the parts tracker from [KROACH] with the gap underneath the metal rail. See Photo on bricklink: https://img.bricklink.com/ItemImage/EXTN/18897.png

Chris Dee wrote me, that Design IDs 2860 and 2862 will be the correct numbers for the 9V track as well.

And he wrote me, that , since I am sure that the all-plastic tracks also uses 2860 and 2862, then maybe the mould was updated to remove the recess. In that case the LDraw convention would be to use 2860a for the version with a recess that accepts the metal and 2860b for the all-plastic version.

So these are the new part submits for the b-parts.

Update ring primitives via script. This will not reset the vote status of the part.

I got the "new" switch and must admit, that this part uses the old mold but the metal rail is missing.
I will rework (or deep check) this switch as well, when I finished the 9V version.

Using common Subfile 2860s01.dat

@Max, for the new 9V Tracks you have used a slightly wider track width (101 LDU) compared to the Plastic Tracks (100 LDU) measured from the center of each rail. Was that by intention? - Because it leads to incompatibility between both worlds. By using this common subfile here there is a small collision between the Switch Blade and the rail. See 53404c02.dat.

I have to rework the PF-Tracks as well.
I did the measuring for the 9V and PF tracks and got 101 LDU for both.
But as written before, I will continue work, as soon as I find some free hours for.
