The local economy is so bad it’s eating into train ridership. MTA’s figure, recently reported down 4 percent, appears to be leveling out, and MTA even holds out hope that it’s not as bad as it looked. But things are worse in Staten Island. The 14-mile Staten Island Railway is on pace for a 6.6 percent ridership drop — this despite such innovations as the Early Departure “Get-a-Way” schedule during the Thanksgiving weekend. The drop is attributed to unemployment, but we suspect the recent introduction of turnstiles at Tompkinsville, preventing those who had been so inclined to get out there and evade paying their fare, may have something to do with it.
