Data from JP Crozet's Franco-Ethiopian Railway site, [], last accessed on 21 February 2009.
Names were Lion, Leopard, Panthere, and Buffle.
NB: Tube length is an estimate based on the calculation of tube surface area by subtracting reported firebox heating surface from reported total evaporative heating surface

Shipped years after the FER's 5-6 (Locobase 9971), this trio of Moguls included replacements for the 7-8, which were lost at sea in 1901. In 1913, the design had a greater distance between the last two coupled axles. A more important difference was the superheater; the two earlier locomotives were updated with this feature.
Names were Elephant, Hippototame, and Fauve.
