From checking the patch notes I was hoping this was fixed, but seems the 375 white version is still subbing into normal 375 blue services. Which from what I remember from TSW3, isn't meant to happen. It's only meant to show up on the ROG services being pulled?
I don’t recall it ever being made solely for the RoG services? Personally I would prefer them to couple only with other white consists, IRL they were only really seen that way.
Personally I don't see a problem with the white 375 subbing into blue 375 services. It kinda adds more variety imo, and there are videos of unrefurbished 375s operating with Refurbished 375 as well
If you go through the live article tab and scroll down to loco pack 2, the screenshots shows it pulling blue 375s as well as white 375s.
It is intended to give variety and I like it, it also fits in with the ROG pulling some away to get refitted, those others running around just haven't had their turn yet.
I actually like it. Wouldn't be the first time I've seen a white 375 in the middle of two blue ones, I find that funny.
