This past weekend, I got to tour the MTA Coney Island Overhaul Shop with the NY Transit Museum. The complex in which it is located is the largest rapid transit yard in North America. They overhaul subway cars with a scheduled maintenance system and also scheduled maintenance that is too intensive for the maintenance shops. They do maintenance on all parts of the subway cars including the electric motor, air brakes, compressors, and wheels and axles.
