A vane cluster (60) has a platform (68), a shroud (72), and at least first and second airfoils (62, 64) extending between an outer face (74) of the platform (68) and an inner face (76) of the shroud (72). Each airfoil has a pressure side and a suction side. The pressure side of the first airfoil (62) faces the suction side of the second airfoil (64). The cluster (60) includes a cooling passageway system. The system includes at least one inlet (110, 112) in the shroud. At least one first feed passageway extends from the shroud (72) to the platform (68) through the first airfoil (62). At least one second feed passageway extends from the shroud (72) to the platform (68) through the second airfoil (64). A first platform cooling plenum (170) is to the pressure side of the first airfoil (62). A second platform cooling plenum (190) is to the suction side of the first airfoil (62). A third platform cooling plenum (172) is to the suction side of the second airfoil (64). A fourth platform cooling plenum (174) is to the pressure side of the second airfoil (64).
