I’ve heard that there are commuter trains from Baltimore to Washington, and that Baltimore real estate is a good bit cheaper than in the Washington DC area. So wouldn’t be surprised if federal workers/contractors are living in Baltimore and commuting to Washington.
Not happening. Even federal drones value their safety.
The problem there is that the train system is so slow and unreliable. Much of the DC Metro system seems to be built on single track and the trains are really slow. Most of my friends that make long distance commutes ride chartered busses. A better way to ride, but still a long commute.
