celebrate its 50th anniversary PHILADELPHIA (AP) — President Joe Biden didn’t want to be anywhere else Friday than helping his Amtrak family celebrate 50 years on the rails. “I wouldn’t have missed this for the world,” he said at Amtrak’s station in Philadelphia, where he used the occasion to plug his $2.3 trillion infrastructure proposal. Biden rode Amtrak almost daily between Washington and his home in Wilmington, Delaware, during his 36 years as a U.S. senator. As vice president, he went home by train most weekends to visit his mother, who was ill, before she passed away. “In the process, Amtrak became my family,” Biden said.
