▶ Watch Video: CBSN President Biden is delivering remarks on Friday to celebrate 50 years of service by Amtrak, the country’s passenger rail system. Mr. Biden earned a reputation for frequently riding Amtrak from Delaware to Washington, D.C. while he was a senator, and continued using the railway as vice president, inspiring the moniker “Amtrak Joe.” Mr. Biden’s remarks come as he continues to promote his multi-trillion dollar legislative agenda. His infrastructure and jobs proposal, the $2.3 trillion American Jobs Plan, would invest $621 billion in improving transportation infrastructure such as roads, bridges and public transit, including $80 billion dedicated specifically to Amtrak.
