The metro rail projects in Tokyo and Hyderabad will have a common communication-based train control systems developed by French firm Thales.
"Thales has been selected by the East Japan Railway Company, known as JR East, to design a CBTC system for the Joban line, in the Tokyo Metropolitan Area. The Hyderabad Metro rail project also has a Thales-developed CBTC system," a Thales release said here.
JR East's objective is to replace its current conventional automatic train control system and acquire a state-of-the-art system with an optimised life cycle cost, it said.
Since the 1980s, Thales has been working on CBTC technology, which was originally developed without the need for track circuits or secondary detection.
