Greece Railways - (WD Nr. 73677) SEK Class Λβ 2-10-0 steam locomotive Nr. 962 (North British Locomotive Works 25403 /1943)
SEK (Hellenic State Railways) Class Λβ is a class of 16 2-10-0 steam locomotives, ex-WD Austerity 2-10-0s purchased after the Second World War. All of them were previously stabled in Egypt and were transported to Greece, as part of the UNRRA mission in Greece (arrived at Thessaloniki port in 16 January 1946). They were given the class letters "Λβ" and numbers 951-966.

The locomotives were mainly allocated to the Salonika division, but hauled both freight and passenger trains (including Athens to Istanbul Expresses) all across Greece, until they were slowly replaced by diesel locomotives in the mid-1970s, being one of the last classes of SEK steam locomotives to be withdrawn from regular service.
