This is a 5 car custom BR 1442 Talent 2 created in formation designer missing rubber bit and wheels between coaches 2-3 and 3-4 but not between coaches 1-2 and 4-5.
This reminds me of the MML EMT when it was released and the video I made, they did patch it and for the most part it is working well. But if this is the result of the patch, not good.
The reason for this is because some on trains like the German ones usually they will be connected by one coach having wheels and the other not so you need to get a coach with wheels for it to have wheels. It can be difficult to do because of how formation designer works but if you try it should eventually work.
