Amtrak Between D.C., Boston at Half Capacity for 4th Day

Amtrak's busy Northeast Corridor will run at half its normal capacity Friday, the fourth day in a row that winter weather has disrupted service.

Amtrak spokesman Marc Magliari says the frequency of the Acela Express and the Northeast Regional lines was reduced by about half on Thursday and Friday because of below-freezing temperatures. The lines also were running at half-capacity Tuesday and Wednesday following a winter storm.

The company's Northeast Corridor stretches from Washington, D.C. to Boston and is the busiest railroad in North America, with more than 2,200 trains operating daily.

Magliari says all passengers have been able to get on different trains after being notified about cancelations. It's unclear when Amtrak will be able to fully restore service.
