If you've ever had the pleasure of sitting in a stalled, sweaty C train somewhere between Hoyt-Schmermerhorn and Jay-MetroTech, here's some good news: the MTA will soon be giving C train cars a $25 million upgrade.

The R32 cars, which mostly run on the C line, are the oldest in the MTA, notoriously dirty, slow, clunky and prone to breakdowns, and had the distinction of being awarded the lowest marks on last month's State of the Subway report card for the fourth year straight. The cars' shiny new upgrades will include better brakes and propulsion systems, graffiti-free windows and better air-conditioning. Just in time for winter!

The upgrades are only temporary; the MTA says they will be replacing the old R32s with new cars in 2014. "The work currently being performed on these cars will help increase customer comfort and insure service reliability until their replacements arrive," Carmen Bianco, the Senior Vice President of the Department of Subways, said in a press release.
