The siding was for the use of the Olympic Club, on the Great South Bay funded by William H. Moffitt, a member of the Olympic Club and a real estate developer. Located on the south side of the tracks and crossing Saxon Ave. Read on:
The Ice factory building would be located (red X) on this 1915 Hyde map Islip segment, below: The Olympic siding was located .27 miles west of Islip station, based upon mileage indicated in the 1913 and 1919 CR4. It was for the use of the Olympic Club, funded by William Moffitt, on the Great South Bay. It was on the south side of the tracks and crossed Saxon Ave.
By 1914, Moffitt was said to have been worth over $2 million and had bought and sold over $20 million in property. He had become a distinguished businessman whose company and accomplishments had been praised in the papers. However, the real estate industry began to decline and Moffitt found himself so greatly indebted he sold his home on Orowoc Pond to Walter G. Oakman, (who in 1918 sold it to George Graham, a senior member of the U.S. House of Representatives) in order to pay his mortgage. Moffitt was also forced to sell a factory he owned in Bay Shore and continued to sell off his assets for the next three years to make ends meet.
Unable to pay back creditors, Moffitt fled to California and then became a fugitive. He had been indicted back in New York with a grand larceny charge as a result of real estate deals totaling $4 million and chose to not appear. Moffitt also spent time hiding in London but did come back to the United States where he was finally arrested and investigated. Eventually, Moffitt was able to pay back his creditors and returned to California where he established another real estate business in the 1920’s. All that was remembered of Moffitt however back in New York was Moffitt Boulevard located in Bay Shore.
His estate eventually became the new Islip High/Middle School location by the lake behind McDonalds on Main Street when it opened 1965 when I attended.
My “guess” with Moffitt in deep trouble financially, but the siding still in place for another 10 years until 1924. The LIRR may have spotted freight cars there for Baileys and a load for the Ice Company (team track style!?) across the street for wagon pickup. Similar to Grinnell Lithograph on Moffitt Blvd over in the area across from the Islip Freight station/later team track. Info: Steven Lynch
