My first summary after playing about 5 minutes:
The quality of the new variants is great. They even made the lightmodes of the CN a bit different (steplights) as it has another lightsystem as the other variants.
I especially like the SD70Mac. Amazing.
(has the same sounds as the ACE)
The BNSF SD70ACE comes even in 2 variants: normal and with Wispercab
And there are again some bugs
-The NS SD70 M-2 (not the others
) has the well-known problem of the right walkway (behind the engineer's seat) disappearing when inside the cab (this is also not fixed for the SD70 Volume 1 pack).
-The SD70Mac seems to lack the Train brake in the F4 controlscreen, although it's there in the cab and can be controlled (same problem as with the Dash 9s)
-2 Standard - Four Minutes of Fun (SanB to Barstow), Black Wheat (Castle Rock)
-2 Carrer - Face the Summit, Return of the Mac (both SanB to Barstow), Springs for the Springs (Castle Rock)
-2 Freeroam - SD70s at Barstow (SanB to Barstow), SD70s at Monument (Castle Rock)
