More than a foot of snow fell in parts of New York City on Thursday, leaving the Metropolitan Transportation Authority with the task of keeping the city's mass transit moving as smooth as possible. 

There were some transit changes throughout the day, as many buses had to avoid icy roads. Some LIRR trains were canceled or delayed. 

By Friday, normal service resumed with a few changes. Here's a look at current weather-related service changes:

Subways

A trains: Southbound trains are running local from 168th to 145 streets due to the Cold Weather Plan.

Buses
