As you can see here https://forums.dovetailgames.com/threads/uk-tocs-round-two-poll.41055/ Scotrail, LNER, GWR & BR all are in round 3 So, now we will decide, what era do we want. Now I'm not going off the eras showing in roadmap codes but more that of the Operator. As for British Rail that will be slightly different.
Sorry folks completely forgot about this, so we have BR (non-polled), East Coast (LNER), Scotrail (First) & Great Western (FGW/GWR)
