One trouble-free year later, New York Air Brake signed a $25 million contract to provide brake systems and controls for New York transit's entire fleet of 754 R46 subway cars, the beginning of over a decade of providing brakes to commuter lines.By 1990, New York Air Brake had furnished $100 million worth of equipment for more than half of New York City's R62A's, R68's and R110A/R110B subway cars before NYAB's Transit Division was established as the Knorr Brake Company and moved to Westminster, Maryland.
