Yes, the NYO always augments the numbers quite markedly; as many string players as they can fit, plus twice as many wind and brass players, almost doubling nearly all the parts, in order to give this incredible experience to as many young musicians as possible. For example, in this particular work, Stravinsky scored it for quintuple winds and brass- ie 5 flutes ( including one piccolo flute and one alto flute), 5 oboes ( including one cor anglais), 5 clarinets ( including one piccolo and one bass clarinet- although the third clarinet also plays a second bass clarinet on occasions), 5 bassoons (including one contrabassoon), 5 trumpets ( including one piccolo trumpet), plus 3 trombones and 2 tubas. The only exception is that he writes for 8 horns.
