According to Boston.com:
"President-elect Barack Obama will journey to the nation’s capital for his historic inauguration by train, his inaugural committee announced today. The trip on Jan. 17 — three days before his swearing-in — is designed to highlight the inaugural theme of "Renewing America’s Promise" by reviving a tradition of presidential whistlestop tours and by stopping in cities crucial to the American story: starting in Philadelphia, where independence was declared in 1776, and Baltimore, where the national anthem was penned to honor the War of 1812. In between, Obama will pick up Vice President-elect Joe Biden in Wilmington, Del."
That’s a great sign for support of trains by this new administration!
