You’ll have to wait for the mod makers to adapt and update.
The Train Fever Mod Manager (from train-fever.net) have been updated so transportation mods (like locos, multiple units, trams etc) will be adapted to the new way mod handling in Train Fever, but it doesn’t make the mods themselves.
Install on your own risk. Let the mod makers get some time to update their work.
I personally haven’t tried the updated mod manager from TF.net, but all I know from reading their forum is that the app will create the needed info.lua file. Whether it populates data and so on, I have no idea.
