Subway meltdowns and hobbled commuter train service defined 2017 for straphangers, who found their day-to-day travel obstructed by the very system driving the city’s economic engine.

Rampant, system-wide delays from signal and electrical system failures in the subway coupled with a repair backlog in Penn Station that required eight weeks of reduced LIRR service, was dubbed the “summer of hell” by Gov. Andrew Cuomo.

Cuomo is looking to tighten the MTA’s belt and prevent funds from slipping away.

A report from the Citizens Budget Commission, a non-profit organization which studies government spending, said a bill to allow bus drivers to give out an extra free transfer to straphangers would see the MTA lose up $40 million annually.

On Dec. 21, Cuomo vetoed the bill.
