ATP on the Class 43 is only (partially) enabled on the AP version available for TSC only. I have no idea why after all this time it could not be done in TSW - and why does the dashboard clock in the MML version not work (or maybe that is prototypical )
And they clearly got in a mess setting up the safety system activation buttons on the MML version as well, no idea why they changed them from the GWG version.
