Hellenic Railways Organisation
When the Hellenic Railways Organisation converted the section Palaiofarsalos-Kalambaka to standard gauge as a branch of the mainline, the metre gauge section from Velestino to Palaiofarsalos was cut off. This section is maintained by the Museum Railways Company or EMOS ( or ΕΜΟΣ). EMOS operates on this section a former SPAP Linke-Hofmann DMU, usually between Velestino and Aerino.
