In yesterdays livestream it was stated that the 314 will come in Scotrail livery but not Abellio Scotrail
I thought that... AFAIK before the Abellio ScotRail Livery they were only in three other liveries and none of them were ScotRail. Blue/grey, SPTE orange & black and finally SPTE maroon and cream.
Abellio ScotRail and ScotRail are essentially the same - the only difference is a sticker on the doors stating that ScotRail is operated by Abellio. I'd hope that both the ScotRail Saltire and SPT Carmine & Cream liveries are included. Only 5 of the 16 units were painted in Saltire Blue (314203, 204, 208, 211, 212) while the rest kept the SPT Carmine & Cream livery and went to the scrapyard wearing it.
If its Scotrail livery before abellio it will be Scotrail blue with the words Operated by First on the doors. You won't get Carmine & Cream because they haven't said you're getting it, only Scotrail blue. All units will probably wear the same Blue livery even tho some of them didnt in real life. It's not exactly prototypical but then DTG are not known for that.
