Hi @tomisnic, Welcome to the Rail-Sim forum!
Are these two freight locos 'stuck' using the passenger designation of the PZB system?
Unfortunantly DTG hasn't built other PZB modes into these locos.
Also, I noticed that the BR189 does not switch pantographs when you switch direction.
I think it is intended to not switch the pantographs if you change the direction, but I could be wrong.
I'm sorry for any english mistakes I made!
