An overview of the DØ Central Track Trigger (CTT) for the Tevatron Run 2 program is presented. This newly commissioned system uses information from the DØ Central Fiber Tracker and Preshower Detectors to generate trigger information for the first level of the three-tiered DØ Trigger. The system delivers tracking detector trigger decisions every 132 ns, based on input data flowing at a rate of 475 Gbit per second. Initial results indicate excellent performance of the CTT. First studies of efficiency and trigger performance of the CTT are presented.
