Who's driving my train?

It's my personal belief that Morgan Freeman likes to drive Metro trains, and takes a vacation to do so every now and then. The other day, I was taking the metro to work, like I do every day, and I noticed that the voice of the driver sounded familiar. It took me from Farragut North to Van Ness, but I eventually realized it sounded exactly like Morgan Freeman. I mentioned it later to Boyfriend, and he said that he had had that same experience a couple of years ago.
