Legacy Locos - Train Sim 4

Hi folks, sorry if this has come up before but I've been away from TSW for a while.
I've finally got around to buying train sime 4. The legacy routes downloaded fine. The locos, however, reufuse to download and gives an error message that the relavent rout needs to be installed first. I've installed them but still the same error.

Any suggestions to resolve this would be appreciated

 

Not sure how to fix on PC
If you're on ps4 or any console I suppose before you use a downloaded dlc had try restarting the console.
You should also make you're you've installed right version as well, on console both the tsw 3 & 4 version download.

 

Thanks for that, when I downloaded the routes both TSW3 and TSW4 versions popped up in the PS4 download list without any input from me

 

Also worth noting is that older locos are tied to their respective routes.

 

all sorted with the help of support as well, thanks folks
