ABSTRACT

This article introduces the fully automatic Communication Based Train Control
System (CBTC). The CBTC has gradually replaced the traditional track circuit
system and has become the mainstream of the modern MRT Operation Control
Systems (OCS) because of the advantages of advanced digital wireless
communication technology, the rapid development of train control software and
hardware, the simplified wayside and the station OCS equipment with
comprehensive functions and the flexibility and expandability of CBTCs.
Moreover, in terms of operation and maintenance time, CBTC is simpler than the
said traditional track circuit.

The first phase of the Taipei Circular Line which as built and completed by DORTS
officially commenced revenue service from January 31, 2020. This project adopts
the Communication Based Train Control (CBTC) system with the highest
automation level of the GoA4 system, and it is also the second CBTC GoA4
system after the Taipei Wenhu line in Taiwan.
