If you've noticed an increased amount of people chatting away as Blue Line trains dive underground, there's a reason for that.
The CTA has completed installation of 4G wireless service throughout the underground portions of the Blue Line, the mayor's office said in a press release obtained by DNAinfo Chicago. This comes after an initial push that brought 4G service to the Blue Line stretch from Logan Square to Belmont going toward O'Hare, which was announced just last month.
The press release said 4G wireless service would be extended to the Red Line in the coming months as well. If all goes according to plan, it looks like work on that development may be completed just as quickly. Once finished, Chicago will be the "largest city in North America to have a subway system with full 4G wireless coverage across its structure," the press release said.
The new service comes at no cost to the city. All funds were provided by AT&T, T-Mobile, Sprint and Verizon.
One line down, another to go.
