Long Island Railroad No. 29 was a G5s class 4-6-0 "Ten Wheeler" built by the Pennsylvania Railroad's Juniata Shops in 1928, for the then PRR subsidiary, the Long Island Railroad (LIRR). The G5s had a driving wheel diameter of 68in and had a distinctive Belpaire firebox.
It was part of the principal fleet of passenger locomotives alongside K4s and RS-3s, the latter of which eventually replaced them.
In 1955, No. 29 was formally retired as the railroad replaced its steam locomotives with more efficient diesel-electric locomotives.
Soon afterwards it was sold for scrap.
