Feds back ambitious plan to speed up Northeast rail service

Federal rail regulators are endorsing an ambitious and costly plan to rebuild the congested Northeast Corridor over the next 30 years that they say will shore up crumbling infrastructure, increase service and speed up travel, with some trains eventually able to reach 220 mph on a stretch of the Washington-Boston route.
The Federal Railroad Administration’s plan unveiled Friday aims to cut down on delay-causing bottlenecks and increase capacity by upgrading outdated bridges and tunnels, including ones into New York City that are more than a century old, and realigning tracks to eliminate speed-restricting curves.
