The Federal Railroad Administration will host a series of public meetings on the future of the Northeast Corridor, including a session in Philadelphia on Nov. 19, at SEPTA headquarters, 1234 Market Street, from 4 p.m. to 7 p.m.

The FRA is preparing a plan for improving the 457-mile rail corridor between Boston and Washington. It expects to come up with a single "preferred alternative" by mid-2015, complete with cost estimates and possible construction schedules.

The goal is to lay out a feasible plan for investing in the nation's busiest rail corridor through 2040, with proposals for updated equipment, more trains, new stations and possible new routes.
