We present transport critical current (Jct) data for polycrystalline films in the TI-Ca-Ba-Cu-O system. Comparable results are obtained for unoriented films of TI2CaBa2Cu2Ox and unoriented and epitaxial films of TI2Ca2Ba2Cu3Ox: namely, Jcts over 105 A cm -2 (109 A m -2) at 77 K with weak sensitivity
