NEW YORK (AP) — Federal transportation officials are gathering in New York to discuss long-term plans for the aging Northeast Corridor rail line.

The corridor experiences regular delays on Amtrak between Washington, D.C., and Boston and on regional rail lines such as New Jersey Transit, due to 100-year-old infrastructure.

At a conference Wednesday in New York, the Federal Railroad Administration will lay out its vision for expanding service and making existing service more efficient.

Proposals range from better integration of schedules and fares for intercity and regional rail lines, to building a second rail line to carry trains at speeds up to 220 mph.

Plans also factor in two new tracks under the Hudson River, a project that was halted four years ago by New Jersey Gov. Chris Christie.
