The train's driver and two supervisors were given two-year prison sentences and fined $70, Ahram Online reported Sunday.
Three other railway workers were acquitted in the case, which involved a derailment in January that also injured 120 draftees.
Announcing its verdict during the weekend, a misdemeanor court in Giza said that while many of the train cars were obsolete the defendants were responsible because they had not properly checked the train.
One of the train's 12 cars, carrying about 200 soldiers, derailed near the city of Badrashin on a trip to Cairo.
About 1,328 conscripts were aboard the train.
Mohamed Fouad, president of the Railway Workers Union, said his organization would appeal the ruling.
