Just me messing about trying to get different formations into the game without using formation designer. Forget about the BR Blue livery........but would 31s and JNAs have 'played' together? (I'm guessing not).
What reason could there be for them not to? I’ve seen a video on YouTube of a 37 hauling some PNAs which, in my mind, are similar enough for me to think maybe it’s not completely unheard of for a 37 and some JNA wagons to play with each other as you put it.
I've still not seen anything obvious that shows 31s hauling JNAs although, as you said, there's no harm in putting the two together for a bit of variety within the game. As you can see I have got a CL31+JNA formation into the game (both loaded & empty) and have also done something similar with the CL37 and a CL08. At some point soon these will be available to use in Scenarios via a mod.
