All aboard! Biden helps Amtrak mark 50 years on the rails Darlene Superville View Comments Philadelphia – President Joe Biden, once a regular Amtrak rider, helped the nation’s passenger rail system celebrate 50 years of service Friday. As a U.S. senator, Biden was a fixture on Amtrak trains between his home in Wilmington, Delaware, and Washington, D.C., when the Senate was in session. He continued riding Amtrak as vice president. He has sometimes been referred to as “Amtrak Joe.” But with a presidential train trip challenging because of security concerns, Biden instead flew to Philadelphia for Amtrak’s celebration at its busy 30th Street Station. He was to be introduced by a conductor who worked the route when Biden was a regular passenger, while the next generation of Amtrak’s high-speed Acela train, scheduled to enter service next year, will be on display.
