Systems from Märklin:
one or the other of you may miss the support of certain functions of the Märklin system in
+Hardware™ 10.
First and foremost the following features would be relevant:

C track turntable

Integration of boosters in the CAN bus of the CS2/3 into the
Booster facility of
TrainController.
These things were indeed on the agenda of
+Hardware™ 10 and were partly implemented. However, according to the current status, they will not be released.
Unfortunately, Märklin is not willing to provide the hardware required for test and reference purposes under the same conditions as all (really all!) other hardware manufacturers do.
We have already been in contact with Märklin several times on this subject. Always with the same negative result. It is quite possible that other software providers act differently on this point. However, we are not willing to work under different conditions for systems from one manufacturer than for systems from all other manufacturers. We have tried several times to achieve other conditions. After failing to do this, we stopped pursuing the above-mentioned functions in the
+Hardware™ 10 project.
But even if it is probably too late for version 10, this could be changed very easily for the future: Märklin only has to do the same as all (!) other hardware manufacturers, but not less.
