This required raising the jackshaft above the plane of the axles, necessitating a more complex system of side rods. In 1956, all eighteen members of class Ce 6/8 III were upgraded and became class Be 6/8 III. As well as standard gauge Crocodiles, there are also narrow gauge versions. The best known are the Rhaetian Railway (RhB)'s metre gauge locomotives of class Ge 6/6 I, the Rhaetian Crocodile. Several of these still run on passenger trains on special occasions. They are also used on freight trains in busy periods. The Bernina Railway (later merged with the RhB) also built a single Crocodile type, the Ge 4/4, nicknamed the "Bernina Crocodile". This locomotive survives and is being restored to operating condition. Two other Swiss narrow-gauge railways also have locomotives nicknamed Crocodiles; the BVZ Zermatt-Bahn (BVZ) (which merged with the Furka Oberalp Bahn (FO) in 2003 to form the Matterhorn-Gotthard-Bahn) uses series "HGe 4/4 I", known as the Zermatt crocodile, while the Chemin de Fer Yverdon-Ste. Croix owns a solitary class "Ge 4/4" #21. Neither of these locomotive types have an articulated body, which leads some railfans to nickname them "false crocodiles". Very similar locomotives were used in Austria as Austrian Federal Railways ("Österreichische Bundesbahn") classes ÖBB 1089 and ÖBB 1189, and are often known as "Austrian Crocodiles". The German classes E 93 and E 94, also used by the ÖBB as series 1020, are sometimes called "German crocodiles". They are sometimes nicknamed "Alligators", instead, because of their broader, shorter snouts. The French SNCF 25 kV AC locomotives of classes CC 14000 and CC 14100, used mainly for iron ore trains on the , have sometimes been called "crocodiles", although more commonly "flatirons". They are different from the Swiss crocodiles in that they are not articulated, but are a single long steeplecab or 'monocabine' with a bogie beneath each end. Crocodile locomotives were also used in India. These locomotives, of series WCG-1, were used from 1928 between Bombay and Pune, and were all built to the Indian broad gauge of 5 ft 6 in (1676 mm).
