The British Rail Class 56 is a type of diesel locomotive designed for heavy freight work. It is a Type 5 locomotive, with a Ruston-Paxman power unit developing 3,250 bhp, and has a Co-Co wheel arrangement. Enthusiasts nicknamed them "Gridirons", due to the grid-like horn cover on the locomotive's cab ends fitted to nos. 56056 onwards. Under its Romanian railway factory nomenclature, the locomotive was named Electroputere LDE 3500, with LDE coming from Locomotivă Diesel-Electrică and the 3500 being the planned horsepower output.
