Apparently the MTA along with refurbishing / reconstructing the escalators at the Roosevelt Island subway station decided we can use some sort of electronic signage down on the station's lower mezzanine. The interesting thing is that the screens face away from the escalators.
One would think perhaps the signs are to be clocks or track indicators but what purpose would they serve as you head up and out of the station. Yes we have a number of folks who work on the island for whom knowing the time etc could be useful but the fact is the great majority of the traffic are commuters heading into Queens or Manhattan.
Stay tuned. If there are anything like the current escalators they will not always be working anyway.
