CTA Plans To Upgrade Wireless Service On Trains

CHICAGO (CBS) -- The CTA says it plans to upgrade its wireless network so passengers can use their cell phones even in its subways and going through tunnels.

The CTA will seek bids to modernize wireless service on the 11.4 miles of tunnels and underground stations on the Red and Blue line.

The goal would be to have the network compatible for all major wireless carriers.

"To be a world-class city, Chicago must have a world-class infrastructure, so that people can get around the city efficiently, safely, and productively," said Mayor Rahm Emanuel. "CTA is investing in all aspects of its infrastructure, from rails to stations to wireless access."

The timing of the project was not immediately known.
