The MTA shined on a dark day.

While city roads were gridlocked, planes were grounded and buses were crashing into each other, the subways and MTA railroads weathered the season’s first snowstorm with hardly a hitch.

Officials said they prepared for the storm by assembling extra workers to clear snow and debris, salt and sand platforms and stairs and inspect storm drains to make sure they were clear.

The MTA blamed slow buses on “massive gridlock.”

Spokesman Jon Weinstein, said workers “fought through epic traffic and kept the subways moving … during a tremendously difficult commute.”
