President Joe Biden — perhaps the nation's biggest Amtrak fan — is promoting new federal investments for trains on the heavily trafficked Northeast Corridor. The Democratic president traveled to Bear, Delaware, where he announced more than $16 billion in new funding that is going toward 25 passenger rail projects between Boston and Washington. Bear is located about 12 miles (20 kilometers) from Biden's home of Wilmington. His remarks were held at the Amtrak Bear Maintenance Shops, where trains are maintained and repaired. The investments, the White House says, will help trains run faster, cut delays and create union jobs.
