I was on the BxM2 yesterday heading home and say a shuttle bus running service for the 
train up Madison Avenue. At first I thought it was a mistake, but the bus was packed. This morning I checked the status update for the subway and saw a TON of changes because of this so-called "NYCT Cold Weather Plan". Now I agree with them shutting down the system because of the storm, but are they seriously going to do this every time it's cold? Seems like a BS reason to curtail service. I mean what happens if it's this cold during rush hour? I don't see the difference. Cold weather is cold weather.
Things like this demonstrate how much subway is going down the tubes. I can't imagine Metro-North being down here because of "cold weather".
