In keeping with tradition of past state leaders, Gov. Andrew Cuomo has at times raided funds from New York City's mass transit system. While his reputation as a leader has been highlighted by on-time budgets, his response to Superstorm Sandy and design-build infrastructure projects that have been completed for less money, the gap in transit spending seems to have finally caught up with Cuomo in 2017. (The Cuomo administration sees things differently, highlighting the funding it has directed to the MTA.)

Two train derailments in the past month and chronic delays on nearly every subway line have made it almost impossible for New Yorkers to get through a single week without major issues. These glaring problems are compounded by the system's grossly outdated mechanics and an agency that the governor is in charge of – the MTA – that has not been held accountable for unfinished capital projects that date back to the Bloomberg administration.

These issues didn't happen overnight. Below is a timeline of the major events that have led to where we are today – for better and worse – under Gov. Andrew Cuomo.
