Nearly 100 inches of snowfall in just a few weeks has paralyzed the nation's oldest public transit system, frustrating Boston commuters who are sharing horror stories of long waits and frayed nerves.

Commuter, subway and Amtrak trains in the greater Boston area were delayed or canceled outright again on Tuesday. Highways were jammed with extra cars as workers tried to avoid the transit system's problems.

A New Hampshire resident said his drive into Boston took more than twice as long even though he started earlier than usual. A Cape Cod resident described a five-hour ordeal that involved being shuttled from one commuter train to another after the one he was riding got stuck in the snow.

And there's no end in sight to the commuting woes: Transit officials warn the system won't run normally for at least a month.
