\r\nBloomberg Radio reports that 23% of New Jersey Transit's (NJT) rolling stock, and 34% of its locomotives, have been damaged or rendered unusable by Hurricane Sandy. Quantitative repair estimates, as well as cost, are unavailable.\r\nBut last Saturday NJT executive director Mr James Weinstein acknowledged that NJT won't be able to resume normal rail operations for at least four weeks, and possibly much longer.\r\nThe operator, which only had a single light-rail line in operation for most of last week and started Northeast Corridor service to Penn Station on Friday, began running trains on three rail lines on Sunday morning.\r\nThe North Jersey Coast Line has resumed limited service to New York Penn Station, operating between Woodbridge and New York; the Raritan Valley Line service is offering a limited service between Raritan and Newark Penn Station, as is the Main\/Port Jervis Line. However, trains originating and terminating in Secaucus and the Atlantic City Line have resumed their normal service between Atlantic City and Philadelphia.\r\nOther railways in the region are also piecing their operations back together.\r\nAmtrak offered a reduced Acela Express and Northeast Regional service on the Northeast Corridor from Boston to New York City and Washington, DC, yesterday. The operator is also continuing to restore the Empire Service between New York City and Albany-Rensselaer by offering a modified schedule.\r\nBy Sunday, New York Metropolitan Transportation Authority offered limited and modified service on all subway lines with the exception of the G line. MTA said that on Monday morning the Long Island Rail Road and Metro-North Railroad offered as close to regularly scheduled service as possible. In addition, limited service was restored to the Staten Island Railway with crews working around the clock to restore other line segments.\r\nMTA Metro-North Railroad resumed full service on all three of its main lines on Saturday. Limited service resumed on Sunday on the Port Jervis Line following a week-long suspension. Metro-North restarted services on its branch lines east of the Hudson River on Monday morning. The New Canaan Branch in Connecticut, which still has severe tree damage to overhead catenary, is being served by buses connecting to train services.\r\nMTA Long Island Rail Road is operating a modified schedule on all branches except the Long Beach branch. Trains on the Ronkonkoma Branch are not operating east of Ronkonkoma and trains on the Montauk Branch will not operate east of Speonk. With two of the East River tunnels operated by Amtrak into Penn Station still out of service due to flooding, a reduced service is in place.
