On April 30, 1997, the Board of the Metropolitan Transportation Authority approved the purchase of 680 cars from Bombardier (the R142s) and 400 cars from Kawasaki (the R142As). The original purchase order was for 740 cars, but because of the intense competition between the firms, the MTA was able to purchase 340 additional cars at the same price. The entire cost of the purchase was $1.45 billion. The new subway cars were based on the results of the tests from the R110A and R110B test trains. The historic deal came after round-the-clock negotiations, and the contract was the largest subway car purchase in the history of the New York City Subway up to this point.
