The domestic railway network is limited to the mainland and is generally slower than travel by road. The Greek railway service is run by Hellenic Railways Organisation - OSE (tel: 14511; www.trainose.gr). Greek trains have first- and second-class accommodation. However, following cuts in 2011, during which several lines were suspended due to financial problems, the rail service is limited to the northern and eastern mainland (the principle route being Athens-Thessaloniki) and to the northern parts of the Peloponnese (at present only the Athens-Corinth line is functioning, but there are plans to upgrade and reopen the Corinth-Patra line).
Overnight trains Athens-Thessaloniki sadly no longer offer couchettes, which were also victims of the cuts.
Trains are cheaper than buses but generally much slower. Reservations are available for no extra charge and there is a 20% rebate on return fares.
International train services were also slashed during the 2011 cuts, and Greece is no longer connected to neighbouring countries by rail. To compensate in part for this, OSE operates a bus service from Thessaloniki-Sofia (Bulgaria).
