The New York Ceutral's World's Fair exhibit passed through this city Saturday afternoon and quite a large crowd assembled to see it go through. It was drawn by World's Fair Engine No. 999, built for exhibition by the Central, an eight wheel passenger locomotive weighing 110 tons which on its trial trip f rom New York to Buffalo made the remarkable fast time of eighty-six and three-quarters miles an hour. The drivers of this engine are seven feet and two inches in diameter. The tires are Si inches thick by 5$ inches wide. The boiler is 58 iuches in diameter at the smallest ring and bas 268 flues two inches outside diameter, 12 feet long. The total heating surface is 1,930 square feet. The boiler is designed to carry 190 pounds pressure per square inch. It was the largest locomotive that has ever passed through this city. But the part of the exhibit which will attract the most attention is the duplícate of the first train of cars run in New York state. The engine is the "Dewitt Clinton" built in 1831. The weight of the engine is 6 tons. The boiler has thirty copper tubes 2J inches in diameter. It is mounted on four wheels 4 feet 6 inches in diameter.

The coaches look very much like the old fashioned stage coaches. They are 7 feet 4 inehes long and 5 feet wide in the center. They have three seats inside. The doors are on the side and a seat on top of each coach. The original coaches cost $310 each.
