  We calculate flavor-changing neutral-current (FCNC) processes involving
top-quark production via anomalous tqV couplings at the Tevatron and HERA
colliders. We cover the FCNC processes p pbar -> t Z, p pbar -> t gamma, p pbar
-> t t, and e p -> e t. We go beyond leading order and include the effects of
soft-gluon corrections through next-to-next-to-leading order. We demonstrate
the stabilisation of the cross section with respect to the variation of QCD
scale, and we investigate the reach of the Tevatron and HERA colliders.
