This would be a dlc I would want to see. The class 320 are currently operating on the Cathcart circle. I think that these will be good because they are cool trains. But if you seen megasims video of the announced class 380, next to it was the class 320. I think it will generally be good for the route and the increase variety in Glasgow Central on TSW
Slightly going off topic, I think that when the new timetable on Cathcart circle is introduced when the 380 comes out. I would love to see 385s at Glasgow Central as I checked on Wikipedia and apparently they ran on the line.
