requires additional funding to expand several sidings before allowing additional service. Another obstacle is freight congestion in Chicago particularly at the 75th Street Corridor on Chicago's South Side. The third obstacle is capacity at the Long Bridge in Washington, D.C.. Infrastructure improvements are being made at all three. The Orange Branch between Orange and Gordonsville raised train speed after the completion of a track and signal project in 2017. The Chicago Region Environmental and Transportation Efficiency Program (CREATE) has received funding under a public–private partnership (P3) for the 75th Street Corridor with construction beginning in October 2018 and is scheduled to be finished by 2025. A parallel span of the Long Bridge is full funded and moving towards engineering design and financing. Starting on October 1, 2019, traditional dining car services were removed and replaced with a reduced menu of 'Flexible Dining' options. As a result, the changes to the consist of the train will have the dining car serve as a lounge car for the exclusive use of sleeping car passengers. In June 2021, Senator Jon Tester of Montana added an amendment to the Surface Transportation Investment Act of 2021 which would require the Department of Transportation (not Amtrak itself) to evaluate daily service on all less frequent long-distance trains, meaning the Cardinal and Sunset Limited. The bill passed the Senate Commerce Committee with bipartisan support, and was later rolled into President Biden's Infrastructure Investment and Jobs Act, which Congress passed on November 5, 2021. The report must be delivered to Congress within two years. Train consist In the early 1990s, the Cardinal ran with the usual Amtrak long-distance consist of two F40s/E60 plus several material handling cars (MHC) and baggage cars, followed by several Amfleet coaches, an Amfleet lounge, a Heritage diner, two or three Heritage 10-6 sleepers, a slumbercoach, and finally, a baggage dormitory car. Following the delivery of the Superliner II fleet, however, the Cardinal was re-equipped with Superliner cars in 1995. As a result, its route was truncated to end in Washington D.C.; then, as now, Superliners could not operate north of Washington due to low clearances in Baltimore and New York City. With the Superliner equipment, the consist would usually be two Superliner sleeping cars, a diner, a Sightseer Lounge, a baggage coach, and a coach. In 2002, two derailments on other routes took numerous Superliner cars out of service. Because of this, insufficient
