Arcade & Attica No. 114 is an RS3M type diesel locomotive built by the American Locomotive Company (ALCO) in 1952, originally for the Delaware & Hudson Railroad (D&H) as their No. 4112. It was originally built as a standard RS3 type, but in 1975, it was rebuilt into an RS3M type. After its rebuild in 1975, it was renumbered to 1976 and repainted into a red, white, and blue paint scheme. It was renumbered again to 506 in 1979 and it remained in revenue service with the D&H until it was officially retired in 1988.
After its retirement from the D&H, it was eventually sold to the Tioga Central Railroad to continue in freight service. The Tioga Central Railroad later moved to Pennsylvania in 1994. It was later sold again to the Western New York & Pennsylvania Railroad (WNY&P) in 2014 and once again renumbered to WNY&P 406. In 2016, it was repainted into the WNY&P's corporate black and yellow paint scheme. It remained in freight service with the WNY&P until it was relegated to yard switching in 2022 and later officially retired from service again.
In 2023, it was sold once again to the Arcade & Attica Railroad (A&A) between Arcade and North Java, New York and later arrived there under its own power in July of that year. It was once again renumbered to A&A 114 and has remained in both freight service and occasional excursion service since July 20th.
