The equipment of the Somali railway was similar to the one used in the
Eritrean Railway.
Steam locomotives Three classes of steam locomotive were used: one design of 0-4-0 shunter and two designs of 0-4-4-0 Mallet for line service.
202 Series These small 0-4-0
tank engines were and are the standard shunter locomotives of the system, built between 1927 and 1937 by the firm of Breda in
Milan. They have short side tanks, a rear coal bunker, and a unified, oval dome containing the steam dome inside a larger sand dome – this arrangement, popular worldwide in nations that favored the sand dome, helped both to insulate the steam dome and to keep the sand dry with the warmth. Large, prominent
builder's plates adorn the domes. They use
Walschaerts valve gear with
piston valves and
superheating.
440 Series One of these early Mallet locomotives, which is a true Mallet and thus a compound, still exists in storage at the Asmara railway station. It was a 1915 product of Ansaldo in Genova.
442 Series locomotive, similar to those used in Somalia These later, and much larger, compound Mallet locomotives were built by Ansaldo in Genova in 1938 to largely replace the earlier types, both the 440 Series and the unsuccessful 441 Series, which were simple locomotives (i.e., non-compound) and found liable to run out of steam on the heavy grades of the line. Like the other locomotives they are tank engines with large side tanks and a rear coal bunker, under cover of the cab roof in this design. These are quite hefty machines, as required by the tough demands of the terrain.
Other trains The Somali railway also used the
Fiat TIBB diesel (TIBB stands for "Tecnomasio Italiano Brown Boveri"). Additionally some small carriages were built locally by "SPA-A" in Mogadishu in 1930 (using locomotive "A-1") which were used for local passenger transport. They had a top speed of 70 km/h. ==Railway stations==
