The city's new bus system, the BaltimoreLink, will be implemented this coming Sunday, and bus riders can expect the buses on their routes to stop less frequently, to require more transfers, or to be eliminated entirely, all in the name of "efficiency," according to the MTA. Add to this a 10-cent fare increase (due to a state law, not the BaltimoreLink itself, says the MTA), color-coordinated lines to memorize rather than numbered ones, and still no reliable bus tracker, and you get quite a few unhappy bus riders. The local bus drivers union, Amalgamated Transit Union Local 1300, has said drivers haven't been properly prepared either. As the MTA prepares to launch this overhaul, its administrator, Paul Comfort, and his chief of staff, Jim Knighton, left abruptly last week. OK, but at least the MTA's letting us ride for free during those first two weeks?
