So, there is a sign at L'Enfant saying that flag stop has been discontinued since July 2020 to maintain social distancing. Not sure how it achieves that--in fact it's the opposite. It's an open air station that is the most secure. If I don't board there, I have to wait for some time in Union Station, an enclosed space.
That said, the train has stopped twice this week to let me off at L'Enfant on 176, going to DC from Charlottesville, but the last time I was the only one and had asked the conductor. So I am not sure that they stop by default, as in the old days, maybe you have to ask for it.
On the way down on 171, we coasted through the station both times and there was no one there. But the conductor told me they don't have instructions to stop there at this point, so you can't expect to be picked up.
I will be calling the corporate office to see if they can reinstate it. There were tons people boarding 171 at L'Enfant pre-covid, there used to be a demand for it!
Plus, as I said, it's safer to wait there than in an indoor station.
