Great Western Express is the only route which I can't install. It still gives error code: CE-107880-4 If GWE can't be installed then you can't install Diesel Legends of the Great Western. Those two are the only ones I can't install....
Wait for an update or in the ps store - https://live.dovetailgames.com/live...0.1041371098.1625868403-1091880617.1544483944
