Br Class 313 Emu

I have downloaded this to my PS5 and cannot find it ? what does it add on to? I am running Train Sim 2 I have west Cornwall rail, and the Great Western Express. Would be grateful for any ways to solve this problem.

 

Do you have east coastway, as you need the add on for the 313?

 

As stated on the PS store page you need the East Coastway add on for the 313 to work, this includes if you want to use the 313 on other routes like Brighton Mainline

313 and WCL aren't even listed in the store for me...
