All rail service at Westport's Saugatuck and Greens Farms stations is suspended today -- and indefinitely -- as part of a broader service interruption between South Norwalk and New Haven in the wake of the Friday evening collision between two Metro-North Railroad trains in Bridgeport, just east of the Fairfield Metro station.

The crash, apparently caused when one of the trains derailed, injured 60 passengers -- six of them in critical condition as of Saturday morning.

The incident, which is being investigated by the National Transportation Safety Board, is expected to cause massive disruption to both rail commutation throughout southwestern Connecticut and the entire Northeast corridor.

No trains are able to move through the area as of Saturday, as the wrecked M-8 Metro North cars must remain at the cash site until the NTSB investigation is done. Once the probe is finished, the train cars will have to be removed from the mangled tracks by crane, according to Metro-North officials.

The accident destroyed a swath of tracks -- bending rails and shattering ties -- along the overpass above Fairfield Avenue in Bridgeport, a short distance from the Fairfield Metro rail depot and the city's border with Fairfield. Overhead power lines also were damaged, the railroad said.

As of Saturday, Metro-North officials said service is suspended -- "until further notice" -- between New Haven in the east and South Norwalk in the west.

No plans have been announced as of Saturday about whether bus service will be provided for would-be riders at stations in the service "gap," including the two depots in Westport.

Meanwhile, Metro-North says reduced, hourly service will operate westward between South Norwalk -- departing 39 minutes after the hour -- and Grand Central Terminal in New York City -- departing 7 minutes after the hour.

No information is available as of Saturday morning whether an alternate service eastbound from Bridgeport to New Haven will be available.

Regular service will operate between Stamford and Grand Central Terminal.

Regular service will be in effect on the New Canaan and Danbury branch lines.

Yankee game day service will operate between Stamford and Yankees-East 153rd St. Station.

Meanwhile, Amtrak reports the Bridgeport collision has crippled its service along the Northeast corridor, suspending service between New Haven and New York City.

Limited Amtrak service is operating only between Boston and New Haven as of Saturday.

Amtrak service is operating as scheduled between New York, Philadelphia and Washington, D.C., the railroad reports.

Shuttle service between New Haven and Springfield, Mass., is also operating as scheduled, according to Amtrak
