The remnants of the hurricane caused roads in northern Quebec to be rutted and eroded by heavy rainfall, isolating the north shore communities for several days. BNSF Railway announced that it expected to restore limited freight service to southern Louisiana by September 1. Other than debris on the mainline, the biggest problem facing crews working to reopen the line is the damage to the Bayou Boeuf bridge in Morgan City, Louisiana. The bridge and bridge piers were struck by a barge propelled by the storm's winds and wave action. BNSF sent crews to repair damaged railway signal systems starting on August 30. BNSF transferred freight through other hubs such as St. Louis, Chicago, and Memphis until service was restored. Norfolk Southern (NS) announced that the majority their mainlines that were damaged by Hurricane Katrina were again operational. They removed almost 3,700 fallen trees and inspected over 1,400 miles (2,253 km) of track before setting trains in motion. Tracks directly into New Orleans, however, remained out of service due to washouts, continued flooding, as well as the city's evacuation orders. Freight that would have normally transferred in New Orleans was routed to other terminals across the NS system. The company's experience with previous hurricanes helped it to prepare action plans before Katrina made landfall. They moved repair equipment, supplies and employees into nearby areas and quickly deployed them to inspect and repair the system after the storm passed. USCG helicopters rescued 1,259 more people off house roof tops to total of 1,609. U.S. Senate passes a relief package. President Bush appeared on Good Morning America, and said that he understood the frustration of Katrina victims, many of whom are still waiting for food, water, and other aid. "I fully understand people wanting things to have happened yesterday," Bush said. "I understand the anxiety of people on the ground. … So there is frustration. But I want people to know there's a lot of help coming." He said that the government's first priority is to save lives, and described the devastation that he saw while flying over the hardest-hit areas as, "very emotional," but was also very optimistic about the prospects of New Orleans' recovery. A 50-member Canadian search-and-rescue team from Vancouver, British Columbia reached a flooded New Orleans suburb to help save trapped residents. National Guardsmen accompanied by buses (475 in all) and supply trucks begin to arrive at the Superdome. A day after the National Guard (from Camp Beauregard) began delivering food, water and ice in New Orleans, the National President of the American Red Cross, Marsha Evans, requested to set up a shelter in New Orleans to pass out food and water.
