For those who are repairing Playmobil train wagons: I have made a PDF file with the most actual part numbers of the two axle wagon frame. This frame is almost unaltered in production since Playmobil makes trains. Older trains has a coupling with a feather, but the new coupling with counter weight will fit on the older axle boxes.
All the parts give you a black frame. Some wagons have a grey or red frame, even on the current website on Playmobil, but to my experience these parts are not available. If you have for example car 5624 with red frame, you have to repair this car with black frame parts.
