There's a lot of construction going on the 1 line these days and we noticed some new subway technology being introduced recently. Earlier on in the year, the new digital signs announcing estimate train arrival times were introduced to the numbered subway lines and it now seems like some fancier technology for each train has come about. We first thought from a distance that an "O" train had arrived in the station on a previous outing but upon closer inspection, miniscule electric bulbs were found forming a circle around the red 1 logo of the car window. The lit up signage must be a new prototype since we haven't seen one since. Is this the new look for all New York City subways?
