So I've started the the Timetable "Extra 02" On Peninsula Corridor with the MP15DC switcher. As I drive along with the wagons on the back, I started picking up speed. At about 30-35mph a "rattling" noise apears. It's massively loud and can only be heard from the inside of the cab, no note of it from the outside. It drives me a bit crazy as it is freaking loud and I actually have no clue if that's supposed to be or if I have done a mistake at preparing the Train... Would be great to see if other people have experienced it.
