SEK class Μα
Encyclopedia
SEK class Μα (or class Ma; Mu
-alpha
) was a class of 2-10-2
steam locomotive
s made by Ansaldo-Breda in 1953. They were numbered Μα1001-1020.
The Μα locomotives were the last ones acquired by SEK before conversion to diesel traction. They were designed and made in Italy by Breda
(10 units) and Ansaldo
(10 units) in 1953–1954, while some parts were made by Nuove Reggiane. The length of the locomotive with the tender was 24.93 m, the maximum height 4.51 m and service weight 136 tn. The boiler operated at 18 bar and their rated power was 2950 hp. Maximum speed was 90 km/h.
Due to various technical problems, only two years after introduction they were modified by Henschel
(1957–1958). The boilers were converted to burn heavy fuel oil.
These locomotives were based at Aghios Ioannis Rentis and Thessaloniki depots and were used mainly for freight trains and for some express passenger trains on Piraeus–Thessaloniki and Thessaloniki–Idomeni mainlines until the early 1970's, when they were withdrawn by the Hellenic Railways Organisation (successor of SEK) due to complete conversion to diesel traction.
