Cell phone service will be getting better on Washington DC's metrorail system soon. Instead of just Verizon, there will be service from Sprint, T-Mobile, AT&T, and Verizon. Also coming access to the internet and wi-fi. Twenty underground stations will have expanded coverage by the end of this year and the whole system will be finished by 2012.
That is good news for riders, but there is good news for metro too. They will get a second network for its operations for free and will get a minimum of 25 million dollars during the 15 year contract.
