Caboose #303 was a wooden side door caboose acquired by the Arcade & Attica from the Susquehanna & New York Railroad. It was one of only three cabooses that railroad ever owned and served as the conductor's office on trains until the mid 1960's. Its side baggage doors made loading mail and freight much easier. This early 20th century caboose was purchased in 1980 from the Arcade & Attica Railroad by Earl R. Rule, who spent many hours restoring it so people could enjoy and appreciate this historical piece of railroad history.
