When I got off the train at Dupont this morning, the platform escalator was disassembled! There is a sign that says it will be put back into service 2/7/10. I will report back to you when it does return to service or if the date is delayed.
When I've seen those "return to service" notifications, the first date is usually pushed back several times -- especially for escalators. But in good news, the three street escalators at the south side of Dupont have been operative all at once for a very long time!
