They were bought in three batches from 1904 to 1923.
FIRST BATCH-1904;
The first EMUs in Greek railway history were ordered in 1901 by the Σ.Α.Π. and were built by THOMSON HOUSTON DE LA MEDITERRANEE.Twenty powered vehicles and twenty trailers were ordered, all Bo'Bo' with top speed around 65km/h.
SECOND BATCH-1914;
This batch contained nine cars built by BAUME MARPENT, similar to the older ones but with some differences in their design.
THIRD BATCH-1923;
The twelve cars that were bought in 1923 were ordered again to BAUME MARPENT but were built in Peraeus works (not Κ.Ε.Π.), so their cost was reduced by 30%.
AFTER THE SECOND WORLD WAR;
After the war ended, the Ε.Η.Σ. decided to rebuild all their electric rolling stock (like ALL the other railway companies did in Greece).So, all the 61 cars were rebuilt.The changes were mostly in the outer part rather than the engines.Their service ended in 1985.They were the powered units with the most years in service in Greece,and imagine that one STILL WORKS.Although most of them still worked in 1985,they were withdrawn because the electricity system changed to 750V.
TODAY;
Today, in 2018 only one six car trainset works.All the others that were not used as ΥΠΗΡΕΣΙΑΚΑ were given to organisations, clubs, libraries etc.. One remarkable thing is also that one powered unit was rebuilt again and became the ONLY ONE electric powered freight car ever built (when I say freight car, freight means that it transferred tools etc. during the night shift when the line is being repaired etc.). The ones that were not given were two.One is in Peraeus and Rentis Depot in bad condition and one is in Peraeus Depot (again not the PDS/SEK/OSE one but the SAP/EHS/HSAP one).The last was used until 2000 in some Sundays.Now, because the electricity system changed again to 850V
, the unit is gradually being destroyed......Another example is/was the XYLINO of Kalamata Park..............
