94 ALSTOM Company ICONIS the Traffic Control Center（TCC）System for DORTS Projects

ICONIS ATS is also able to support different types of signaling system, such as:

˙Fixed Block：where train location is based on track-circuit status delivered by the
interlocking system and optional, Positive Train Identification（PTI）data delivered by the
Automatic Train Control（ATC）system. Fixed Block is used by MTR in Taipei.
˙Moving Block: where continuous transmission of train location and identification is
received via bi-directional radio communication. An underlying fixed block system may
provide track-circuit statuses, which provides additional information on train location for
fallback train tracking in case of radio communication link failure.
