It’s that time of year once again when, on its best days, the public transit system is relegated to a crude pneumatic tube belching hot air through the bowels of the city. We can add to that the now frequent occurrence of trains being delayed or stalling for prolonged periods of time. And then, of course, there were the three frightening derailments that have transpired since March. The truly incredible obsolescence of this integral system has been laid bare, the ugly truth plain for all to see. And no amount of half-measures–duct tape or bubble gum–can fix the mess. Andrew Cuomo’s “Summer of Hell” is in full swing.
