Amtrak to New York City and Albequerque, NM. Our locomotive caught fire in Syracuse and we were pulled to Chicago by a Conrail loco. The Toldeo, OH, Amtrak station looked like vacant parking lot that hadn't been repaved.
MBTA commuter rail, subway, and street car for commuting to work, school, and downtown. The drawbridge at North Station got stuck in the up position (I hoped to get home early that afternoon; no such luck). The locomotive of the train in front of us caught fire; our train had to push the other train.
Washington DC subway to go from hotel to National Air & Space Museum. The last time my disabled wife and I went to DC, there was no station near our hotel that had working escalators or elevators.
NY/NJ Path between World Trade Center (before 9/11) to Exchange Place, Jersey City, NJ. NY Subway from World Trade Center to Mulberry Street, Little Italy, NYC.
