The highs of a train pulling into the station immediately as you swipe your MetroCard are matched in intensity only by the lows of being a second too late and having the doors close in your face. Somewhere in between is pacing around, staring into the tunnel and hoping to see a light. Knowing for sure when the subway is coming won’t be easier anytime soon, with the MTA announcing yesterday that despite fare increases, countdown clocks at stations will not be expanding beyond the numbered lines for at least three to five years. Wireless Internet, meanwhile, won’t be in all stations until 2018, at which point a single ride will cost approximately $19.99.
