Transportation officials: smooth commute after Connecticut rail crash NEW: Officials: People stayed home, took Monday off, or are waiting to see how things go NEW: "We scared the heck out of people, and it worked," transportation official says (CNN) -- Commuters who would normally take the train between New Haven, Connecticut, and New York braced for the worst Monday after a derailment that disrupted train service on one of the busiest tracks in the country. Connecticut Gov. Dannel Malloy had suggested that Monday morning commuters should telecommute or carpool, and said they should expect "substantial delays." But at 9 a.m. Monday, there were no lines of people and there were plenty of shuttle buses to take passengers around the 2,000 feet of bad track. Starting at 4:30 a.m., buses carrying 40 to 55 passengers each left Bridgeport, Connecticut, for Stamford. "We scared the heck out of people, and it worked," a Connecticut Department of Transportation official on site said. Officials say either people stayed home, took Monday off, or are waiting to see how things go. Even traffic flow was said to be normal for a Monday commute. One Metro North employee with direct knowledge of the head count told CNN that the roughly 2,000 people who took the train from New Haven, Conn. to Bridgeport Monday morning were "far, far fewer than normal." Federal investigators are trying to determine what caused Friday's derailment of a northbound Metro-North train that struck Metro-North train that was headed south. John Cappiello, a spokesman for Bridgeport Hospital in Connecticut, said three patients were still there Monday -- one person in critical condition and two listed as stable. Several officials at the tracks Monday morning wondered whether the number of commuters would pick up Tuesday once passengers saw how things went. Amtrak released a statement Sunday night saying that service between Boston and New Haven, Connecticut, also would be limited, and "there is no estimate on service restoration." All the rail cars had been removed from the accident site by Sunday afternoon, Earl Weener of the National Transportation Safety Board said. "This gives us a chance to see how effective the new standards are," Weener said.
