PC Dlc Question

I'd like to purchase the Class 52 to use on the updated WSR, and I see two options. #1 would be to buy the loco by itself, option #2 would be to buy Diesel Legends. I'd prefer to buy #2, as I'd get more use out of the DLC, but am unsure if this Class 52 would be the same one to get the updates on WSR.

Can you please tell me if #2 would work ok for the updates?

 

Only the WSR 52 will appear on the route so go for option #1

 

Thanks Mikey
