The Niagara Frontier Transportation Authority (NFTA) provides bus and rail service to Erie and Niagara Counties. In Erie County, this metro service is delivered via 38 interwoven bus routes and one light rail line. Service extends out to many of Buffalo’s outer-ring suburbs but is concentrated within City limits and runs most frequently during peak hours. The NFTA also provides special transit service to disabled riders, riders attending special events, and metro pass holders in need of emergency transportation. Riders have the choice of purchasing single passes, day passes, or month passes.
