Bug with DBSetXLw

[TTDFan_DN]

Hello. Help me please. I have TTDPatch alpha 60 and DBSETXLw. Configuration in patch vagonspeed on. For freight wans this option are working, but for pasanger and mail vans - it is'n work :
1) If I use locomotive with cobstructial speed greather then 140 km/h for mail and passanger van (local line) train speed is 160 km/h, but max speed this vagon type is 40 km/h. What is the bug
2) If I use locomotive with cobstructial speed greather then 160 km/h and passanger and mail vans main line (max speed=160 km/h), this train have locomotive speed speed (For example If I use ECE1 train speed is 281 km/h, if BR182 - 220 km/h) But max speed this type van is 160 km/h. How it might running with this speed/ It is unrealistic. What a bug?
P.S. Thank you for answer for my question and sorry for my bed English

That's a feature, not a bug.

When trains provide livery overrides for their wagons, the wagons' max speed gets ignored.

The reason being that in this way one single vehicle ID would be sufficient for many different coaches having different max speeds (and other technical data like capacity or loading amounts).
