The WFC also created a scale model of the fairground. The LIRR constructed a siding from the Port Washington Branch, allowing trains to deliver material. At a luncheon in March 1962, Moses lamented that construction had fallen behind schedule. The WFC had allocated $6 million to advertise the fair by mid-1962, and Deegan predicted that the fair's participants would spend another $75 million of their own money on promotion. The WFC also tried to attract Latin American countries to the fair. By late 1962, exhibits for the fair were being finalized, and many pavilions were under construction. Either 68 or 71 nations had announced plans for exhibits at the fair by then, though only 35 countries had formally leased space. Additionally, 125 businesses had expressed interest, and the WFC had finished installing utilities on the fairground. At the end of 1962, a small number of state and international pavilions were being built, while work in the industrial and transportation areas was further along. Groundbreaking ceremonies were hosted for many of the international pavilions.
