The “Ne-Ha-Sa-Ne” was a unique inspection locomotive constructed at Schenectady in 1896 for the St. Lawrence & Adirondack Railway. Weighing nearly 80,000 pounds and equipped with 63-inch drivers, it combined respectable performance with luxurious accommodations. Its passenger compartment, furnished with mahogany paneling and carpeting, seated six occupants. The locomotive was sufficiently powerful to haul the 120,000-pound private car of William Seward Webb, promoter of the railway.

Entering service in 1896, it soon became New York Central & Hudson River No. 49. In 1901 it was transferred to the Rutland Railroad and renumbered No. 100, only to return to the New York Central in 1905 as No. 33. After receiving a rebuilding in 1911 that involved only a new firebox, it rejoined the Rutland in 1914. On this occasion it was assigned the number 99 rather than its former number 100. The locomotive's unusual career reflected Webb's influence over the railroads involved, as he was the leading figure behind all three companies and is said to have used the engine for his personal travel.
