I think that the UAC Turbotrain would be a unique addition to TSC as we dont have many oddball units available to drive. If it were to be added, here is what it would include: Two 9 car sets, one in a VIA scheme, one in a CN scheme One 5 car set in a Amtrak late scheme Finally, three 3 car sets, one in a Penn Central scheme, one in a Amtrak early scheme, and one in a UAC demonstrator scheme. You could also use the consist creator to make the CN 14 car set as well. A bonus could be Canadian Nation IC-34, the intermediate car with added luggage space. anyways here are some pictures.
I hope they will add this finally. That "was" very unique and iconic gt multiple unit. Sadly they scrapped all sets
