                                       • Critical part of US transportation
                                         infrastructure.
                                       • More than 150,000 miles of
                                         mainline rail routes.
                                       • Moves more freight than any
                                         other rail system in any other
                                         country.

                                       • The failure rate has the potential
                                         to cause property damage and
                                         loss of life.
                                       • Lack of maintenance and delays
                                         in repairs has translated into
                                         soaring construction
