I'll add them to my backlog, but my backlog is kinda full at the moment and my time is sparse the coming week(s).
Perhaps you can find someone in the official Discord that can help you quicker. :)

It would be best if you could design the BR 423 and BR 430 for me, because I am not good at designing and need it for the trains in the game... But of course I will link you that you have done the designs. I will publish them then...

Hey Deniz, how would you like me to help you?
I understand some German, but my knowledge of terminology may not be so good. I prefer to reply in English though. :)

Hey TKR i am german and hope we can talk in german but first in english:

I need your help, can you give me the 423 design and the 430? for Nimby Rails, I will put you in the description.... Can we talk and exchange?
