Publication dans Tiflet, Rabat-Salé-Kénitra, Morocco

Hello lovely people. I am planning to backpack through Morocco towards north morocco. But wondered about best way of travel! And I really want to try the train at some point. I tried a couple of websites to find out times and prices for tickets but it not showing it. I wanted to try and get a train from Casablanca to rabat and then from rabat to meknes. I would appreciate if someone knows about this well and could tell me the locations or what to type when looking for train stations.
