Following the recent 50th anniv. livery release I saw there was a static 662 as well as the one I was driving. This was adjacent to track 10 in the Boston Depot (see below)
I think it might be because it’s a livery option and not randomly generated. I can see that causing the problem
Yes, I was driving one and saw 2 others at South Station (Series S). I had read that the delay in releasing was to prevent this, but apparently not. There is only one Trainbow in SEHS. Of course, you can't select whether you get that one or not. If given the choice, I think I would prefer that to seeing the 662 everywhere.
DTG should've used the system they used for SEHS where you get a random chance of spawning in with 662
