A system (10) is provided for sealing a gap (12) between a transition exit frame (14) and a vane rail (18) at a turbine inlet (20). The system includes a seal (11) with a compliant seal member having a generally u-shaped profile to provide a sealing function in an axial direction. The compliant seal member includes a U-shaped inner sheet (28) securely pressed within a U-shaped outer sheet (26). The outer and inner sheets include spaced-apart segments (30, 32) in a lateral direction which are spaced-apart by misaligned slots (36, 38) to block passage of air there through. The system may also include wear resistant material (62) interposed between the seal and the vane rail. A lateral gap between adjacent exit frames may include a plurality of ribs defining valleys and tips, with crushable material disposed between the valleys and tips.
