Why does the 1 train have no AC?

The MTA says less than 2 percent of its cars lack AC. But the 1 line has some of the oldest cars and they're harder to repair. Legacy cars have HVAC units that are located on the underside of the chest where they are vulnerable to debris and dust and tracks, the MTA says.

This means the trains must operate at much slower speeds to safely travel. Snow, freshly fallen or in days-old drifts, produces its own set of problems. It can get sucked into the engine, where it then melts and shorts out major components.

When a winter storm hits and the snow piles high in fluffy drifts, do railroads get a snow day? Despite being an outdoor operation, the answer is no. Even when ice glazes the landscape or temperatures dip dangerously low, railroads run 24/7.

Like mentioned above, the rails aren't really affected by ice or snow. They are just chunks of metal. The biggest issue that rails face is the cold. Rails are restrained by rail anchors from expanding and contracting due to temperature changes.
