Jamais fait, j'ai trouvé déjà ceci sur internet :

Oriente) to Castelo Branco
From
Lisbon to Castelo Branco by bus: Take the Metro from the airport to Seite Rios. Express bus at 09:50 (all working days and Saturdays - if not a holiday) from "Terminal Rodoviario de Seite Rios" in Seite Rios (near the
Lisbon Zoo) to Castelo Branco. Change to the bus to Monsanto at 12:25

Comme trains directs de Lisboa
Oriente à Castelo Branco aujourd'hui par ex, (selon le site des trains suisses) départ à 8 h 24, 13 h 24, 16 h 24, 19 h 24. Trains Intercity, trajet = 2 h 41, celui de 16 h 24 est un Régional, durée 3 h 28. Je n'ai pas les prix, faudrait regarder sur le site des trains portugais. Le Régional sera peut-être moins cher.
