Brazilian Metro Rail Buys P25 System from Tait (3/4/10)
CPTM selected Tait Radio Communications to supply a 16-site digital Project 25 (P25) conventional network. The network will consist of base stations to provide coverage to CPTM platforms and rail lines, mobiles for installation into CPTM trains and vehicles, and portables for CPTM personnel.
The agency needed to invest in a digital radio communications technology supported by multiple vendors. CPTM is responsible for the transportation of nearly 2 million people who commute around the metropolitan area of the São Paulo state every day. The state government allocated US$12 billion to improve and extend the metropolitan rail network. The expansion will include the purchase of new trains, the modernization of railway stations, an upgrade of the signaling and telecommunications system, and an extension of railway lines to make the network four times bigger.
The platform’s base stations will be configured to directly connect with a Zetron console system via an analog interface. Tait and Grupo MPE will integrate a new signaling and telecommunications system to reduce passenger travel time and the intervals between trains from six minutes to three minutes.
